Since today, a new chapter will be released, this second part can not be long. Yet, I wanted to share my latest observations before the publication of chapter 83.
In the first part, I focused on the origins of the champion’s breathlessness and its cure: the amusement park. However, the air was not the only important element in episode 82. Let’s take another look at this image: 
(chapter 81) The plane soars not only above the Alps, but also above a vast river (probably the Rhône)— two landscapes that silently echo the dual composition of breath itself. Breath is made of air and water: oxygen and vapor, wind and moisture. 
(chapter 82) In that sense, the clouds surrounding the aircraft are not mere weather; they are the perfect union of the two elements that sustain life.
Joo Jaekyung’s breathlessness, then, is not simply a physiological lack of oxygen — it is the absence of water, the missing element of tenderness and flow. The champion has spent his life breathing air devoid of moisture, surviving on discipline, pride, and control — a dry atmosphere where emotion cannot condense. 
(chapter 82) That’s why, when Potato offers him a bottle of Evian, he doesn’t even look. He doesn’t need the water from the mountain and as such the world; he needs the water of the body — the intimacy, the shared moisture that reconnects him to life itself. What he truly longs for is Kim Dan’s saliva, the living trace of water transformed into affection, into care, into exchange. 
(chapter 81) He is longing for his lips and as such a kiss.
Only through that bodily element — through the return of water inside air — can he breathe again fully. Dan’s body literally rehydrates him. The vapor that once escaped his lungs returns as mist, as breath shared between two beings. At the same time, it teaches him how to breathe properly, the reverse of this scene in the locker room. 
(chapter 15)
And this elemental union anticipates the next landscape: the amusement park, where the air is filled with laughter, humidity, and movement. 
(chapter 82) Many attractions — the Ferris wheel, the fountain rides, the water park zones — combine air and water, height and spray, just like breath itself. And now, you understand why the champion got wounded with the spray 
(chapter 49) It corresponds to the negative version of the “breath”.
Another possibility is that they first share the same drink or the same ice cream 
(epilogue), because doc Dan wants to ensure that the drink or the ice cream is okay. 
(chapter 82) When Jaekyung and Dan enter the funfair, they’re not simply having fun; they’re reliving the chemistry of respiration and affection — the inhalation of joy, the exhalation of fear, the splash of renewal. The park becomes an externalized lung, a circular world of rides where water and air, play and life, are finally reconciled.
The Castle as Fairy-Tale Threshold
In the amusement park, the castle (chapter 82) stands as a replica of every child’s first dream: a place where danger ends, where curses lift, where the beast becomes human. In this new setting, the ring is replaced by an amusement park — a space where joy is no longer born from suffering. 
(chapter 15) The arena that once fed on pain, blood, and hierarchy gives way to a landscape of shared laughter, circular motion, and renewal. Here, entertainment is not built upon the exhaustion of bodies but upon their liberation. The crowd no longer watches to see who will fall; they rise and descend together. 
(chapter 82) People are more focused on their own emotions and experiences.
For Joo Jaekyung, this shift marks a fundamental redefinition of performance itself. The fighter who once turned agony into spectacle now experiences movement as play. The wolf who fought to survive in the ring learns to live among rides, fountains, and lights — spaces where the body moves not to conquer, but to feel.
Thus, the amusement park becomes his anti-ring — a sanctuary of reciprocity, where elevation and descent belong to everyone, and no one bleeds to entertain the rest. For Joo Jaekyung, who has spent his life trapped in the cycle of competition and rage, walking into that space with Kim Dan is an act of symbolic initiation. He brings the doctor — his witness and healer — into a world he has always avoided: fantasy, gentleness, illusion.
The wolf who once prowled in underground gyms now enters a castle built for children, and in doing so he accepts the possibility of becoming a fairy-tale prince — not by winning, but by transforming.
Why the “First Kiss” Matters Here
A fairy tale’s turning point is always the kiss — the moment when the spell breaks. And you might recall that I came to associate Kim Dan with Sleeping Beauty and in the illustration of that analysis, I 
I placed the doctor’s birthday. And that’s how I remembered here the boy’s huge smile and joy. 
(chapter 11) And now, pay attention to the number of the next episode: 83! The two numbers combined together make 11! As you can see, the amusement park is the most natural setting for a smile and kiss. Joo Jaekyung could even speak about his first kiss, an intimate secret that even Kim Dan doesn’t know. Confessing it there would align his personal myth with the fairy-tale architecture around him. This would make doc Dan realize that he is special contrary to the green-haired ex-lover. 
(chapter 42). But there’s more to it. In episode 81, Doc Dan rejects the champion’s advance — he turns his head away
(chapter 81) letting the lips slip past him like water. Yet, in the very same scene, he allows a kiss on the neck, a place where breath, warmth, and pulse converge. 
(chapter 81) He never pushes him back. The doctor resists with the face — with speech, with identity — but not with the body. (chapter 81) And so, at the end, the athlete moves upward, trying to reach the mouth, trying to taste what remains forbidden. But he fails.
(chapter 81) Why? Because the lips are not mere flesh; for Doc Dan, they are the visible border between desire and love. Jinx-lovers will remember his quiet request in the locker room (chapter 15): he links the lips to the heart — and through it, to the notion of consent. 
(chapter 15) To kiss him there is to ask for entry not into his body, but into his feeling.
That is why the scene at the pool stops at the threshold. The champion can touch his skin, but not yet his soul. 
(chapter 81) The water envelops them both — fluid, intimate — yet the final element is still missing: agreement, the meeting of air and will. Until Jaekyung learns to ask, to replace taking with invitation, the kiss will remain suspended, like a breath held underwater, waiting to surface into love. And now, you comprehend why he couldn’t achieve his goal in the swimming pool. It was, as if he was trying to recreate the situation in season 1. In other words, I deduce that there will be a confession before a kiss happens!!
From Wolf To Prince
A Jinx-lover noticed the similarities between this scene 
(chapter 17) and the one in front of the amusement park: 
(chapter 82) The two scenes mirror each other like opposite poles of Joo Jaekyung’s evolution. In both, he is dressed in black — a color that once signified anonymity and danger, but later becomes the mark of calm confidence.
In episode 17, the champion hides behind darkness. The cap pulled low conceals his eyes, his face is half-shadowed, and his clothes absorb light rather than reflect it. 
(chapter 17) When he intervenes to save Kim Dan from the loan sharks, he is first mistaken for one of them — a predator among predators. The irony is sharp: the man who comes to rescue looks indistinguishable from those who harm. The fighters’ world has taught him that power and fame must be hidden; he was encouraged to hide, as if the fans would attack him. He chose anonymity, unaware that this would not only isolate him but also make him appear as a thug. And don’t forget how the manager called him initially: 
(chapter 75) He is a monster. It was, as if the manager wanted to hide the “wolf” from people out of fear that he might attack people randomly. But the problem is that by dressing like that, he was no different from Heo Manwook. Therefore his heroism passes unnoticed, interpreted as violence and intrusion. 
(chapter 18) Like Batman, he moves in secrecy, protecting without ever being thanked. The outfit explains why his good deed leaves no trace of gratitude — the savior looks like the aggressor.
By episode 82, the transformation is complete. 
(chapter 82) He still wears black, but the darkness no longer hides him. The cap now sits higher, revealing his eyes and mouth — the organs of emotion and speech. A necklace gleams at his throat, a quiet emblem of openness. He walks beside Kim Dan in daylight, not to fight but to share joy. The man who once lurked in alleys now stands beneath the sky of the amusement park, where black absorbs light rather than extinguishes it.
The contrast encapsulates the metamorphosis of the wolf into a prince. And how did Heo Manwook call him? 
(chapter 17) A princeling! He was mocking him, because he knew that the fights were actually rigged. That’s why he called him fake. 
(chapter 17) This new connection reinforces my theory that the schemers are anticipating the Emperor’s demise. 
(chapter 82) Thus Arnaud Gabriel’s words are full of irony. There’s no luck in this match. However, the antagonists are not anticipating a metamorphosis. The wolf hides and strikes; the prince reveals and protects. The wolf saves without witnesses; the prince loves in full view. In the ring’s darkness he fought to survive; in the park’s brightness he learns to live and love. And the moment Joo Jaekyung is freed from his curse and can breathe, his next game will be different. Why? It is because the champion has another reason to make doc Dan’s wish to come true: they should work together for a long time! And observe the power of Doc Dan’s angel on the Emperor after spending his first night with his “bride”. He was full of energy! 
Where his earlier anonymity made his goodness invisible, his new transparency makes tenderness possible. The same man, once mistaken for a criminal, now smiles like a fairy-tale hero. The cap lifted from his eyes symbolizes the lifting of his own blindness — he can finally see and be seen.
The Floating Duck Syndrome
However, contrary to the Sleeping Beauty or the Mermaid, we have two men as protagonists. So there is no princess. It is important because it signifies that we should expect two metamorphosis at the amusement park. That’s why it is difficult to say who will confess first. Nevertheless, this weekend, I discovered the following article: Floating Duck Syndrome. Psychologists use the expression floating duck syndrome to describe people who appear serene on the surface while paddling frantically beneath the water to keep themselves afloat. The image is both graceful and tragic: calm above, exhaustion below. It captures the condition of those who have learned to survive through composure — who equate love with performance and stability with silence.
Emotional exhaustion. Pretending everything is fine, constantly feigning calm and serenity, requires enormous energy. The mind remains in a state of constant tension, trying to control gestures, words, and emotions to conceal what’s really happening inside. Over time, this inner vigilance generates a profound exhaustion that even physical rest can’t alleviate.
Anxiety and perfectionism. Trying to ensure everything is always in order and goes according to plan fuels a constant fear of failure. Many people who suffer from “floating duck syndrome” live in fear of being “found out,” feeling as if they are playing a role that isn’t theirs. As a result, they tend to scrutinize every step they take and exaggerate every stumble. This level of self-demand doesn’t drive excellence, but rather anxiety, because nothing ever seems good enough.
Great frustration. A study conducted at the University of Cambridge revealed that people who experience the “floating duck syndrome” often develop enormous frustration. The problem is that, being aware of the effort they are making, they tend to expect greater rewards and recognition. However, since they project a more carefree image, this recognition often doesn’t materialize, leading to frustration and resentment.
Fragile self-esteem. When we believe our worth depends on projecting an image of success and serenity, any mistake is experienced as a threat. Self-image becomes a facade that must be protected at all costs, relegating authenticity to a secondary role. Consequently, external recognition replaces self-knowledge, weakening self-esteem, as researchers from UIN Walisongo Semarang have found.
Emotional disconnection. Pretending to be okay for too long ends up disconnecting us from our emotions. In the long run, we lose the ability to recognize what we feel and why, which prevents us from properly managing that discomfort. The result is often a kind of emotional numbness that seems like protection, but in reality, it prevents us from healing. Quoted from https://psychology-spot.com/floating-duck-syndrome/
This is Kim Dan’s illness in miniature. Ever since childhood he has floated through life without showing the effort beneath. The grandmother’s silence taught him that visible pain is shameful; the bullying taught him that vulnerability invites attack. So he learned to glide — polite, deferential, self-effacing — while his legs beat desperately under the surface. His smiles are survival reflexes, not joy. His stillness is not peace but tension. And we should see the picture of Kim Dan with his grandmother as a reflection of this Syndrome. 
(chapter 65) so he is not standing on his own two feet. And remember that according to me, Shin Okja stands for shore. He is smiling as if everything is fine, but the reality is different. When Dan sits on her lap wearing the duck shirt, he seems safe, grounded, “held.” Yet the shore (the halmoni) isn’t truly stable — it’s brittle earth pretending to resist erosion. She gives him the illusion of safety, not the reality of it. The hydrangeas stand for temporality. The body contact replaces emotional transparency. What he learns in that moment is: “If I stay still and quiet, she’ll hold me.” Thus, his first emotional rule becomes immobility and silence. That is how the floating duck is born — not by moving freely in water, but by learning to suppress movement to preserve attachment.
The floating duck explains why he could live beside death for so long — the dying grandmother, the dying puppy, the dying parts of himself — without ever asking for help. He confuses endurance with dignity. When the champion first meets him, he sees only the surface: the quiet doctor, calm as water. 
(chapter 56) He doesn’t yet see the storm and suffering beneath.
Parallel Currents: The Prince and the Duck
As Joo Jaekyung rises from wolf to prince, he travels from hidden aggression to open affection. And by doing so, he encourages to see activities as something fun. So far, Kim Dan sees such a day more as a burden and not as a source of joy. Why? It is because he still views himself as the champion’s physical therapist and nothing more. 
(chapter 82) But in such a place, it is, as if time was stopped. Thanks to the many emotions and sensations, his body and heart will be revived. Through fun, the duck will change. As Kim Dan ascends from floating duck to swimmer and to a flying duck, he moves from hidden suffering to open breath. Thus the Ferris Wheel will have definitely an impact on him. Both arcs revolve around air and water — the two elements that make up breath and emotion. Don’t forget that the doctor embodies the clouds as well, while the athlete stands for steam.
In the early episodes, Dan’s relationship to water is defensive: he stays afloat but never dives. He cannot trust the element that once carried his grief. Jaekyung, conversely, dominates air — he owns every breath in the ring but cannot breathe freely outside it.
When the champion teaches him to swim and later to have fun, their roles merge: the man of air brings air to the man of water. Dan’s first genuine strokes are also his first act of rebellion against quiet despair. He is no longer a duck faking serenity; he is a swimmer choosing motion. Thus he can start flying. And now, you comprehend my illustration. 
From Survival to Freedom
The floating duck syndrome ends the moment visibility becomes safe. For Kim Dan, that safety arrives when Jaekyung learns to play — when the arena turns into an amusement park, when life stops demanding perfection and begins inviting joy. Play, after all, is what ducks do when they are no longer afraid of drowning: they splash.
Thus both men’s journeys converge.
- The wolf learns tenderness.
- The duck learns courage. Hence he has the strength to fly on his own and can join the clouds.
- The air learns moisture.
- The water learns breath.
Together they compose the complete lung of the story — two halves finally synchronizing. The one who once hid in darkness now walks in light; the one who once floated in silence now swims toward sound. And this can only happen, when both feel grateful toward each other. 
(chapter 45)

(chapter 66) they saw it as further confirmation of their perception—reinforcing the idea that he is terribly flawed. However, a deeper analysis suggests that this term reflects not just his character but also his evolving mindset and struggle with emotional vulnerability. This essay will explore the paradox at the heart of their dynamic—how both men refuse to acknowledge the emotional weight of their relationship, leading to a cycle of denial and misperception. It will examine how the concept of the jinx evolves, the continued influence of Park Namwook’s manipulations on Joo Jaekyung, and the role that mutual ingratitude plays in their emotional stagnation.
(chapter 2) This belief system dictated that, no matter what, he had to have sex with a man before every match—reinforcing the illusion that he could manipulate fate through repetition. The identity of his partner was irrelevant; what mattered was the act itself, which he perceived as a necessity rather than a choice. This routine provided him with a sense of control, but it also underscored a fundamental reliance on external factors rather than his own abilities. In Chapter 65, however, a subtle shift occurs. While the champion has not dropped his belief yet: 
(chapter 65), the nature of his principle has changed: 
(chapter 65)The athlete is admitting his dependency on doc Dan. The jinx is now directly tied to Kim Dan, not just as a concept but as a tangible element of Joo Jaekyung’s career stability. The second switch is that sex is no longer a condition to ward off bad luck. In fact, the celebrity is recognizing the importance of his daily training and, as such, his hard work. 
(chapter 65) The inner thoughts of the sportsman reveal that the champion is feeling less powerless than before. His champion status is no longer reliant on superstition but on tangible efforts—his “old routine” and, crucially, Kim Dan’s expertise as a physical therapist. This marks a significant transformation in his perception of Kim Dan, whom he now values for his professional skills rather than as a mere tool for maintaining a ritual. Thus, Joo Jaekyung should be less inclined to request Doc Dan’s sexual services. Then, in episode 66, a new change became visible.
(chapter 11), a tool to generate money and maintain the gym’s reputation. Hence he blames him, when members leave the gym. 
(chapter 46) The manager used the incident with Seonho to justify the desertion of the other athletes. However, it is clear that some left the gym because they didn’t become successful like Joo Jaekyung. However, their lack of success is explained by their lack of talent 
(chapter 46) exposing the lack of ambition and commitment from the two hyungs. It is clear that Joo Jaekyung’s wealth and fame was used to attract the sportsmen creating a myth that they could experience the same success. Nevertheless, as time passed on, the fighters were confronted with reality. It was, as if the athlete’s achievement had become a curse for Team Black. Nonetheless, neither the manager nor the coach can admit it, the champion’s bad temper is utilized to cover the mismanagement within the gym. Striking is that by portraying the protagonist as a person with a bad temper and personality 
, (chapter 9) the manager and his colleague described their boss as defective. The contrast between Joo Jaekyung’s perception of ‘defect’ and the coach’s view of him as a ‘maniac’ is particularly telling. When the protagonist refers to Kim Dan as having a defect, there is an implicit acknowledgment that something can be repaired or improved. In contrast, Park Namwook’s statement about ‘handling that maniac’ suggests that the star is beyond fixing—someone who must be tolerated and controlled rather than understood or helped. This fundamental difference in perspective reveals how deeply the manager has shaped the champion’s self-perception, reinforcing the idea that he is nothing more than a force to be managed rather than a person who can change or grow.
(chapter 54) 
(chapter 66) His presence is necessary to maintain the “myth” alive. 
(chapter 66) In calling Kim Dan ‘defect,’ Joo Jaekyung is unknowingly projecting his own self-perception onto him. The term suggests something broken but also something that can be repaired, reflecting an unconscious shift in his perspective. Instead of simply using Kim Dan as part of a superstition, he is beginning to see his vulnerability, perhaps even recognizing a parallel to his own struggles. His choice of words also reveals his deeply ingrained belief in self-reliance. 
(chapter 66) Kim Dan’s nighttime distress contradicts this principle, as it suggests an inability to be alone. This mirrors Joo Jaekyung’s own realization in the garden 
(chapter 66) Nevertheless, the idiom (“he’s got a defect”) reveal that Joo Jaekyung is still under the manager’s influence. This means that this shift is not immediate or conscious; it is restrained by his continued loyalty to Park Namwook and his ingrained avoidance of emotional vulnerability.
(chapter 60) This scene represents the exception. For the most part of the time, the star only visited the gym because Park Namwook had contacted him. 
(chapter 54) 
(chapter 66) Striking is that by each meeting, the champion was alone with the manager. The latter was no longer followed by coach Yosep. It was, as if Park Namwook wanted to have some privacy with the celebrity. However, through this contrast, Jinx-lovers can detect a certain MO from the manager: he is isolating the champion, limiting his interactions with other members. This explicates why he remains a pivotal force in Joo Jaekyung’s stagnation. 
(chapter 66) Yet, just moments later, he tells him that he can take more time to rest, as if feigning concern. This contradiction is striking because it exposes his underlying agenda: he wants Joo Jaekyung back in the gym but doesn’t want to appear forceful. Instead, he makes it seem like Joo Jaekyung is the one making the decision, fostering guilt by implying that his long absence is unnatural.
(chapter 52) His sudden shift—acting as though the champion is no longer himself—reveals his inconsistency. When Joo Jaekyung was compliant, he was simply a reckless athlete with an attitude. Now that he is exhibiting autonomy, Park Namwook implies that something is wrong with him. It was, as though he was missing the old version of the champion. 😂 But this is what he complained about him in the past: he was a workaholic! 
(chapter 27) This double standard highlights Park Namwook’s true role: he is not a supportive figure but a handler, ensuring that Joo Jaekyung remains under control and fulfilling his duties as a fighter. His words are not meant to provide genuine support but to keep Joo Jaekyung tethered to a system where his worth is defined solely by his success in the ring. 
(chapter 54) or (un)favorable interviews about the athlete. 
(chapter 54) 
(Chapter 57) As a manager, Park Namwook’s role involves overseeing Joo Jaekyung’s career, securing contracts, and ensuring his reputation remains intact. Yet, as seen in Chapter 66, his actual concerns seem remarkably narrow in scope. 
(chapter 48) Back then, there was a witness, Kwak Junbeom and the latter could have reported to the “hyung”. These incidents indicate a consistent effort to control what the champion knows, raising the critical question: why?? His silence on this matter suggests not only a strategic decision to keep the star uninformed, but also an attempt to avoid responsibility. The supervisor often hesitates to make decisive choices 
(chapter 50), preferring instead to remain passive so that any negative outcomes can be blamed on the champion. At the same time, this passivity helps him maintain control—as if Joo Jaekyung, without his guidance, would be left ‘alone’ and directionless. In this way, the man with the glasses sustains a dynamic in which the champion feels dependent on his presence, even as he is subtly undermined. By neglecting to inform him of these events, Park Namwook ensures that the champion remains unaware of external factors that could influence his choices. This pattern reinforces the possibility that Park Namwook was aware of the meeting with Choi Gilseok and deliberately ignored it, likely expecting that Joo Jaekyung would take care of it, while absolving himself of responsibility. 
(chapter 66) This hesitation stems from deeply ingrained beliefs about relationships and fidelity. His loyalty to Park Namwook prevents him from fully confronting the possibility that his manager may not have his best interests at heart. Moreover, his own emotional repression makes it difficult for him to recognize his evolving dependency on Kim Dan as something beyond physical necessity. 
(chapter 22) They had heard about his place, for the manager must have talked about it. The protagonist is not someone who will talk about his private life to others. The manager must have dangled promises in front of them, making them believe that if they’re lucky enough, they too could live like the champion. However, their reactions reveal something crucial—they are not motivated by greed but by genuine admiration. They simply want to experience the luxury once in a while, reinforcing that their bond with Joo Jaekyung is rooted in camaraderie rather than material envy. This further highlights the contrast between Park Namwook’s manipulation and the sincere regard his teammates have for him. This scene is important, because it exposes the manager’s prejudices and lack of discernment. 
(chapter 46) Not everyone is the same and more importantly like him! It is clear that the man is projecting his own principles onto others and in particular onto the champion. 
(chapter 66) Neither of them fully understands how to acknowledge care or support. Just as Joo Jaekyung struggles to recognize his actions as stemming from concern 
(chapter 66) rather than routine, Kim Dan fails to see Joo Jaekyung’s interventions as genuine help. This mutual misunderstanding deepens the emotional rift between them, ensuring that both remain trapped in their own perceptions of obligation rather than connection. In Chapter 66, he openly expresses frustration, stating, 
(chapter 66). This moment highlights a rare glimpse of honesty: he is not acting purely out of self-interest, but he frames it as an obligation rather than a choice. From my point of view, such a statement could only reach the physical therapist’s mind, for in the latter’s eyes, the champion has always been a “demon”: self-centered and inconsiderate. Observe the absence of reply from the “hamster”. He couldn’t contradict the star, as the latter was using this negative image: bad tempered and selfish.
. The reason is simple. He was portrayed as someone who would do favors to people constantly: his grandmother 
(chapter 53), the manager 
(chapter 7) and even Choi Heesung. Hence the latter called him like that: 
(chapter 30) Kim Dan’s perception of himself as an “angel” has long shaped the way he interprets his relationship with Joo Jaekyung. Reinforced by his upbringing and Park Namwook’s subtle manipulation 
(chapter 36), he has unconsciously placed himself in a position of moral superiority. He is the patient, understanding figure, while Joo Jaekyung, in contrast, is violent 
(chapter 1), selfish, and emotionally stunted. However, this self-perception is deeply flawed. By believing himself to be inherently better 
(chapter 64) than the champion, Kim Dan avoids confronting his own emotional repression, his weaknesses, and his own form of “defectiveness.” He fails to see that he is just as human—just as fragile—as the man he silently judges. 
(chapter 66) The expression “Really…?” is not just about disbelief but also about a moment of confrontation with reality. Up until this point, Kim Dan has been dismissing his own suffering, suppressing his struggles, and functioning on autopilot. However, hearing a professional confirm that he is indeed sick forces him to acknowledge what he has been denying.
(chapter 60) or exaggerations. 
(chapter 66) It also forces him to consider that others—especially Joo Jaekyung—were right to be concerned, which in turn may lead to a shift in his perception of the champion’s actions.
(chapter 20) with shame, something impure that should be avoided or hidden. This internalized belief made it difficult for him to separate his own experiences from moral judgment. When he encountered the champion —who treated sex as nothing more than a professional ritual 
(chapter 66) He assumed once again that the star had taken advantage of his “drunkenness”, something Kim Dan had done himself in the past.
(chapter 65) Symbolically, this reflects their respective journeys. The demon (Joo Jaekyung) is slowly leaving the underworld of detachment and blind routine, stepping toward vulnerability. Meanwhile, the angel (Kim Dan) is descending from his idealized, self-righteous perception of himself, recognizing his own flaws, desires, and limitations. Both must step away from their extremes—Kim Dan from his unconscious moral superiority and passive victimhood, and Joo Jaekyung from his emotional repression and transactional mindset.
(chapter 40) , while Kim Dan, conditioned by years of emotional neglect, sees gratitude as a transactional exchange rather than an expression of genuine appreciation. 
(chapter 66) because Kim Dan does not recognize his efforts, while Kim Dan cannot see past his own survival instincts to notice that Joo Jaekyung’s actions are slowly shifting from obligation to care. Kim Dan, conditioned by years of neglect and survival-driven thinking, does not see Joo Jaekyung’s actions as genuine care. 
(chapter 66) And the latter can see beyond the appearances.
