It would be great if you could make some donations/sponsoring: Ko-fi.com/bebebisous33 That way, you can support me with “coffee” so that I have the energy to keep examining manhwas. Besides, I need to cover up the expenses for this blog.
After reading the title, you are probably thinking that this analysis will be about his tragic past. But no… not really, as my focus will be what makes the lord happy and unhappy. As you know, weakness can be negative or positive, like for example chocolate is my weakness and as such many weaknesses are connected to the low-born. Thus I chose different scenes as illustration for my affirmations concerning this topic.
Right from the start, we can observe how Baek Na-Kyum’s face become Seungho’s first and important weakness. He is literally glued to the painter’s face, in particular his hair and his eyes. That’s why in chapter 1, the noble is willing to lower himself and touch his face the moment he sees the painter crying.
Look how gentle and caring he is in this situation, although they have just met. He acts in a similar manner in chapter 26 after the forced sex. He doesn’t like it, when the painter is crying so much.
Here he does show some concern again with the same tenderness. Moreover, the image of the painter’s face full of tears (from the chapter 1) left a deep impression on the main lead so that while having sex with Jihwa at the pavilion, he remembers the artist’s visage. 
(chapter 3). Fact is that he is so drawn to his face that he can’t help himself to caress the lips or cheek (e. g. chapter 12)
or the hair 
(chapter 16)
(chapter 35). As you can observe, the master is so attracted by the painter’s beautiful head and face that he always looks at him and even feels the need to touch him. Furthermore, the seme made sure that the commoner would keep his pretty visage without a scar that’s why the former asked Kim to put the ointment directly on his lips after the straw mat beating. This signifies that he even ordered medicine for a simple commoner outlining that Seungho was willing to do anything as he was attracted to his face. And let us not forget that this happened before the seme and the uke made love. The obsession for his face is also confirmed directly by the noble, when in the chapter 31, the protagonist declares that he knows that Baek Na-Kyum has been attracted to him.
This is a proof that his eyes were literally fixed on the artist all the time, even when he was having sex with others. I sense that the eyes are the biggest attraction for the main lead which I will explain further later.
I believe that beauty is not just the only explanation for his fascination. Baek Na-Kyum is so transparent which the noble feels refreshing. Despite the lies and the insolence, Yoon Seungho is capable to perceive the young man’s innocence. Everything in him is exuding sincerity. However, even if the low-born is so easy to read, as time passed on, he becomes the biggest puzzle to solve. Even at some point, Seungho has reached the point that he has to admit that he can’t win this guy over. Imagine, the powerful and fearless lord was almost defeated by such a pure commoner. Why does he find his transparency so interesting? It is related to the world and society he grew up with. All the nobles we saw are or were scheming and manipulative. His so called friends like Min made the “suggestion” to Jihwa to kill the “lover” and the red-haired noble Jihwa played a trick on Baek Na-Kyum by damaging a painting. Then the teacher Jung In-Hun is so fake that he copied more or less a poem from a famous poet and finally his own father betrayed him too. He experienced treachery from his closest relative hence he mistrusts nobility generally. That’s why he doesn’t care about standard morals and etiquette as they are fake. Yoon Seungho is very cautious with people from the same social status, since he has got used to their fakings and schemes. The lord had already felt the naturality and genuineness in those paintings, then he experienced it again with the painter. The latter stands in opposition to the nobles Seungho mingles.
But the lord is not just weak in front of the artist’s face, eyes and his purity, he has a softness for his reddening and tears. Unlike Jihwa who hides his feelings and thoughts behind his closed eyes, his smiles and his rude remarks, Seungho is able to see honest and natural emotions on someone’s face for the first time. As you can observe, the facial expressions are another reason why Seungho fell for the genuine artist. He is able to see that Baek Na-Kyum can’t control his emotions and thoughts. For the first time, our seme is confronted with real emotions through the facial expressions and the gaze. And it definitely helps him to reconnect to his own feelings which had been repressed for so long. Therefore as the story evolves, the more expressions the lord is able to make: he smiles more
(chapter 12)/
(chapter 35), his eyes are shining or if he is so angry, his gaze gets so dark.
It was as if his eyes became weapons so that he would kill someone with them. 
(chapter 30). The beholder is witnessing more and more expressions coming from the lord, while he was so detached in the beginning, when he was sitting in his room looking out of the window. Through Baek Na-Kyum, our seme learns to discover his inner emotions, that’s why we can say that the uke serves as a mirror unconsciously. The eyes were definitely working as a mirror. Baek Na-Kyum showed his sadness, true desires, anger, happiness and thankfulness… a full range of different emotions. But our seme needed to learn how to control them as he had not been used to feel anything for a long time.
But let’s return to the observation mentioned above. Seungho falls for Baek Na-Kyum’s blushing. Each time, he sees the man reddening because of him, he is happy or feels better, just like in the chapter 35.
Although he was terribly fatigued, he couldn’t restrain himself from smiling, when he saw (chapter 35) the painter’s reaction. I could use the scene in chapter 39 as another example. In that scene below, he hears from the low-born that he is blushing because of him.
That’s why he starts teasing him. So this blushing is first connected to his face and secondly to his honesty, which reinforces the idea that the face as such plays a huge part in his falling in love.
The other weakness is that simple words coming from Baek Na-Kyum have a great impact on the protagonist. He is so affected by his comments that he behaves differently. First, he is truly bothered by Baek Na-Kyum’s critic, when the latter reminded him that he was just a man consumed by lust. 
(chapter 5) Hence he can’t even have sex with Jihwa the same day. Let us not forget that these words were told the day before and the noble had not taken these too seriously. However, this time the critic is not said because the uke is upset but because he is serious. During their exchange, the low-born is trying to say the opposite: he is not a man consumed by lust. So he is lying, yet as I mentioned before, the lies are so transparent that they are no real lies. In other words, the uke didn’t realize that he was in reality reproaching the man to be obsessed with sex. The innocent reminder did the trick. Seungho has now something to think deeply.
Then we have this terrible scene in the bathroom (chapter 26), where Baek Na-Kyum is brutally honest with the lord. While the latter tried to put the blame on the artist that everything happened, because he had accepted the proposal and mistaken him for the teacher, then the low-born replies with such a honesty that Seungho can no longer hide from the truth:
He dares to tell the tyrannical master that he is the one responsible and deep down, the lord knows that he is right. Remember that he didn’t respond to the kiss immediately in chapter 20. Look now how shocked the noble is. His honesty makes it impossible to reply. He is left speechless. No one has ever dared to be so frank and he knows that deep down he can not deny it. Then Baek Na-Kyum yells at him how much he hates him.
This triggers the lord to grab his sword and announce him that he is about to kill someone.
He doesn’t even need to give the identity of the future victim. As you can observe, Baek Na-Kyum’s words have such a power over the lord. He can’t help but react to these reproaches or critics. If we compare this confrontation to the one with Jihwa, we can perceive a huge difference. Seungho is always able to reply and even have the final words, whereas it is not the case with Baek Na-Kyum. And in each time, the painter’s gaze played a huge part in it. Here, he could see the hatred reflecting in these eyes and he couldn’t bear looking at them any longer. He had no response to this harsh reply. Then the most important scene where the beholder can witness the power of Baek Na-Kyum’ s words is in chapter 41. While crying, he begs the lord to leave him alone. He uses the imperative twice so he acts as if he has the upper hand. He gets so upset that he ends up yelling at him.
Furthermore, with his words he is rejecting the lord’s presence. However, Seungho kept holding his hand and forced the young man to show his face because he wanted to see his eyes and facial expressions. Pay attention to the first facial expression when he observes the painter crying.
He is honestly worried and must feel the urge to console him. That’s why he wants to look at the painter’s face because he knows that his facial expressions will reveal the cause of his distress that’s why he refused to listen to him. Here, he acts like a lover full of concern for the painter. However, the way he is rejected upsets the master. I believe the slap was triggered for two reasons. Until chapter 41, we always saw the protagonist being very lenient towards the uke’s boldness. By reminding him of his status, Baek Na-Kyum can’t push the man away. As you see, he used the slap as a way to stay by the painter’s side. Furthermore the reproach Baek Na-Kyum expressed that he did everything he wanted. He was following his order: he painted as requested. However, Seungho was no longer interested in the paintings. He is longing for the commoner’s love. So here again, the noble is reminded of their actual situation. The painter is just an employee hired by him. The words Baek Na-Kyum screamed provoked a certain reaction: he used his status in order to be able not to follow the painter’s wish, besides the uke’s words did reflect the truth. They had a master-servant relationship. On the other hand, the lord wanted to comfort him in the beginning, until he saw the picture of In-Hun and comes to a different conclusion. He believes initially that it is related to the departure of the teacher, then that the painter has been asked to sleep with the lord on In-Hun’s request.
The other weakness is Baek Na-Kyum’s erection. The rich man is desperate to be the cause of his erection. Hence he tries to stimulate him in chapter 31.
The expression “for me” at the end of the sentence emphasizes the expectation of the noble. He wants to be the cause of his sexual desires. Now, you can understand why the lord was so happy to see that the commoner had an erection because of him in the chapter 36. We all know that the real trigger for his erection is the aphrodisiac but if he hadn’t been sexually aroused by the lord before, I doubt that this would have ever happened.
That’s why he is smiling with this erection. He is still careful in this chapter because he knows about the weak constitution of painter but he is very insecure about Baek Na-Kyum. He has no idea how he could improve their relationship. So the erection helps him to provoke pleasure in his sex partner. He knows that it is important for the uke to feel ecstasy so that he will be accepted as his partner.
In other words, Baek Na-Kyum seems to be his weakness: his face, his eyes, his facial expressions, his words and his genuineness are the causes why he fell hard for the painter. But this is not the end. The protagonist has other weaknesses which were revealed in the first season: the shaking hand, the nightmare and the insomnia. They are all mostly related to his family and past. Striking is that only Baek Na-Kyum is able to witness all these reactions. He saw the exhausted face in the chapter 35, 
(chapter 35) indicating a certain lack of sleep, then the shaking hand with the fist,
while the lord was talking in a confident manner in front of his brother Seung-Won. He is definitely hurt by the request from his brother because he is reminded of his own past. Yet he can’t reveal anything: his own suffering and what really happened back then. He has to suppress everything and the shaking hand with the fist outlines the resent and frustration. Finally, he asks the young man to sleep with him. He hugs him in his sleep, however he seems to suffer from a nightmare.
Yet he has to hide all of this in front of his servants and other nobles because this could be used against him. He is not allowed to reveal his vulnerability. I come to the conclusion that his hidden vulnerability represents another weakness.
Yet, though the painter has become the biggest weakness for Yoon Seungho who fell in love with him, I believe that he will become his biggest strength. Yoon Seungho will be forced to leave his lethargy behind and even to meddle with politics and officials, since Baek Na-Kyum has been able to evoke true protective instincts. Therefore the weaknesses I listed above are actually positive aspects. All of this proves the deepness of the master’s affection. This is not just a physical relationship.
On the other hand, it seems that the lord’s vulnerability will be one of the reasons for Baek Ny-Kyum to fall in love with the lord. First, he was already attracted to him right from the start. Secondly, he noticed the straightforwardness of the lord. He never deceived him (even with the warnings and the blackmail) so that at some point he even started listening to his words. Because of him, he starts questioning the teacher’s true intentions. He has finally accepted to be by Yoon Seungho’s side. I also think that in the second season, Baek Na-Kyum will discover new sides from the lord: his intelligence and education. I am even expecting that Yoon Seungho teachs the uke himself how to read and write so that he can be called “learned sir” and replaces the teacher totally.
(chapter 43) Here he is described by his friend with a black heart. However, in the first season, he was shown in different chapters (8, 9, 19, 33, 36, 41 and 43), but he was among others and as such, he was never properly introduced. His presence increased until the chapter 43 marking a pivotal moment. In the first version of this essay, I desired to prove that Min would play a bigger part in the second season. And this was proven correct. Nevertheless, I still need to introduce him. But who is this man, what do we know about him in the first season?
(chapter 41) and even put his other hand on his waist. 
His gestures towards our seme revealed something in my opinion. The waist is a very intimate place. It gave the impression that Min was interested in Yoon Seungho sexually. It was, as if this man wanted to become Yoon Seungho’s lover as well. The gesture is quite deceiving, which explains why Yoon Seungho thought that lord Min was wooing him. However, the protagonist was misinterpreting the gesture and interest. In truth the noble was lusting after the painter. This explains why Yoon Seungho was not sensing the danger coming from the “friend“. But then why doesn’t Jihwa feel threatened by him? Then remember that he grabbed Seunho’s wrist. A man in Asia will usually grab his girlfriend’s wrist. In other words, the man with the green robe was treating him like a woman (the waist, the wrist). Everything was pointing out that he wanted Seungho to be his uke. Yet, the reality is that he wanted to “screw“ the main lead. He wanted to ruin him out of jealousy. He desired to have the painter. “Screwing“ someone can have two different meanings. But there‘s more to it which I will explain more below
(Chapter 33) As conclusion, anyone observing the scene in chapter 41 would come to the conclusion, that this man wanted to have Seungho as lover, just like Jihwa, but in a different role. He would like to be the top. As conclusion, the lord Min was a seme who seemed to be interested in Seungho. Thus he considered Baek Na-Kyum and the red-haired master as rivals, whom he needed to eliminate. And that‘s how Yoon Seungho perceived his gesture and words in the woods. This explicates why he compared him to Lee Jihwa. In the main lead’s mind, Black Heart was paying attention to his every moves and was always updated about his interactions with the painter out of jealousy. The reality is that Min was terribly envious of the main lead. His real center of interest was in truth Baek Na-Kyum. Thus he kept looking at him during their first meeting. 
(Chapter 8) 
(chapter 9)
(Chapter 36) Naturally, here Kim had played a huge role in this deception too, as he allowed to leak information to the red-haired master’s servant. 
(Chapter 41) Yet, Min knew that Jihwa wouldn’t be able to resist and run to the lord’s mansion. He had already calculated that the childhood friend would discover the truth. He would be hurt and realize his mistake. He even ridiculed Jihwa by comparing him to a dog. 
(chapter 43) Here, he reminded me of Seungho with his sarcasm and his ironical comments from chapter 6. 
(chapter 6) He enjoys making fun of Jihwa and is as cunning as Seungho, though in reality the main lead‘s true personality is totally different. 
(Chapter 43)
(Chapter 33) It was, as if he wanted to ensure that the artist meant nothing to the protagonist. As you can see, the vicious man gave the impression that he was jealous of the painter. His reproach towards the main lead sounded similar to the childhood friend’s. 
(Chapter 18) 
(chapter 41) It was, as if he wanted to play with Jihwa and get rid of Baek Na-Kyum at the same time. The latter is viewed as a source of danger, for Min keeps thinking about him. The noble considered the artist as a witch who put a spell on him, Here, he was projecting his own thoughts. 
(Chapter 43) It looked like both ukes represented a threat. He was definitely using Jihwa so that if anything would go wrong, only the red-haired aristocrat would be blamed. The man with the black heart tried to diminish the consequences of the murder. He said that the murder should look like an accident, hence this attempted murder can never happen at the mansion. Back then, I had envisioned that they would wait, until Baek Na-Kyum left the mansion, and this expectation was proven correct.
(Chapter 43) He had already anticipated Jihwa’s reaction. While Min declared that it was funny, when Jihwa came crying, he added that he was disappointed that he only saw just tears. He wanted him to “come with his tail between his legs”. 
(Chapter 43) The words the man with the green robe said had a huge influence on him. Not only his mind is black, but also his heart which outshines this man’s evilness and dangerousness. Let us not forget that he is a seme… but since he has been forced to be the bottom because of Yoon Seungho, all his actions can be judged in a different light. People could see him as someone who has been longing to become the main lead‘s lover. Thus he said this in season 2: 
(chapter 52) and in season 3 
(chapter 92) But this was just a deception, his real target was the painter. However, after season 3, I realized that in truth, Black Heart had only been a puppet himself, though Min seemed to be like a personification of the devil… his lies, his words in order to incite Jihwa to commit a crime, his words ridiculising Jihwa and even Seungho.
(Chapter 16) Here, the main lead desired to discover the painter’s sexual preferences. So when Min stroke the main lead’s waist, he never realized the true signification of his action.
(Chapter 41) The main lead could only assume that Min was interested in him, he wished to become his only partner. Deep down, he desired to become the top, but since Yoon Seungho was not willing to change his position, Black Heart was willing to remain a uke. Note that Min invited the main lead in chapter 19 to the kisaeng house, and offered him wine, right after the main lead had cut ties with his childhood friend. 
(Chapter 19) It was, as if he was wooing him, hoping to take over Lee Jihwa’s place. Then in chapter 33, Min is the one asking for Baek Na-Kyum. 
(chapter 33), he would seek his company 
(chapter 51) 
(chapter 52) and he was jealous of the painter, for the protagonist was only paying attention to him. 
(Chapter 101) Note that he even pushed Lee Jihwa to become a top. 
(Chapter 100) It was, as if Min was not interested in the painter at all. His true goal was to get rid of Lee Jihwa and Baek Na-Kyum, his rivals. But we know the truth… Black Heart wished to be noticed by Baek Na-Kyum, thus he said this to him in the shaman’s house: 
(chapter 99) But if he wanted to become his lover as uke, he would be not different from Jihwa. However, this man is definitely not seeking for Seungho’s love. His actions and words don’t fit the profile of an uke, of a person longing for Seungho’s love, rather he fits the profile of a hunter and player. 
(Chapter 56) But Min was still in denial, hence he justified his requests as an urge, while he was also longing for the painter’s affection.
(Chapter 43) And remember that Jihwa is a noble… and in the bible, God got aware of Adam’s original sin, hence the latter was banished from paradise. Thus I had been expecting that Lee Jihwa would lose his title as noble, as his crime would be discovered. And this prediction became true which the author revealed in the creator‘s note. 
(chapter 41) A mouse is small and has no real claws. This shows that Yoon Seungho was underestimating him, but also was misinterpreting Black Heart’s action. He was acting like a jealous concubine, thus he compared him to Lee Jihwa. Here, we had the impression that the protagonist was well prepared. He thought, he knew why Min asked him to bring the painter for their sex party and why the lord Min asked about the veracity of the rumor about the incident at the tailor shop. But no… he didn‘t detect the longing and envy from Black Heart towards the painter. I compared him to a snake due to his cunning behavior and his cynical and seductive words… But the reality was that he was a fool himself, for he had no idea about Yoon Seungho‘s past. The abduction did occur and this twice, but note that Min had to become involved himself in order to achieve his goal. The irony is that when Min said this to Yoon Seungho 
(chapter 102), he was again giving the impression that he had acted like a jealous man who was longing for Yoon Seungho‘s attention. He had acted like a vicious concubine, but in Joseon, „jealous concubine or queen“ would get sentenced to death, like the Queen Yun and the concubine Jang Ok-Jun. 
(chapter 101) No one in his right mind would torment a loved one like that. Yoon Seungho was not recognizing what jealousy and envy are and what these emotions could trigger people to do! Black Heart would torment Baek Na-Kyum, for the latter was rejecting him. So imagine the king‘s reaction, when he discovers that Min got killed. 
(Chapter 102) First, he lost his loyal helping hand, secondly he got misled and even betrayed by Lee Jihwa. In other words, the opposite had happened. Instead of obtaining Yoon Seungho, the king lost his “wife“ who decided to kill himself. To conclude, the villain from season 2 and 3 was in reality a pawn, the shadow of the true villain, lord Song. This explicates why Min‘s behavior was particularly ambiguous in season 1… All his actions and words could be perceived as a jealous man who desired to become Yoon Seungho‘s top!! The king would have never approved such a thing! And this could be the other reason why he will vent his anger on the Lees.
chapter 19
, Yoon visits the painter’s study because he heard from the servants that the painter wouldn’t leave his room and would keep painting without eating much. As you can see, the lord pays a lot of attention to the mental health of the painter. He knows from the way BNK is acting that something is wrong. The reason for BNK’s strange behavior is that BNK had just heard before from Jung In Hun that he was born to be a prostitute. His love for In Hun was so pure and for the teacher, BNK was just a prostitute. 
(chapter 40) The main lead was definitely hurt. Nonetheless, Seungho never witnessed their conversation, unlike in the chapter 19. And in this chapter (19), the rich lord thought that the expensive bottle of wine that had disappeared had been snatched by the painter due to his emotional state. Since the aristocrat had already figured it out that the painter was upset, he decided to visit the artist’s chamber. In other words, in both cases, the lord showed some concern about the painter, and wanted to keep an eye on him. At the same time, he desired to discover the truth about the missing bottle of wine
While he criticizes the painter’s kiss in the chapter 42, this would not arouse him, in the earlier chapter he made no complaint. He saw it as an opportunity to finally taste the painter. He was not annoyed by the lack of inexperience unlike in the chapter 41. However, both kisses have something in common. Both outline BNK’s innocence and purity. These kisses are not here to excite the partner but to express a deep and pure love (chapter 19) or to ask for warmth and comfort (chapter 41). 
(chapter 41), he would have sex with the seme without any preparation. The lord is actually surprised by BNK’s actions because this doesn’t resemble him at all. He acts as a prostitute that’s why Seungho asks if the teacher has talked the painter into it. 
(chapter 42) He is no longer suppressing his homosexuality and he is accepting to have Seungho by his side. Just thinking about In Hun causes pain to the painter here, while he was in ecstasy in the chapter 20. He even wrinkled the painting of the ceremony with In Hun which shows the huge pain in his heart. 
(chapter 41) For him, paintings are treasures. This gesture reveals some changes in BNK. The painter is well aware that the teacher has abandoned him as the former doesn’t want to assume any responsibility. Therefore, his disrespect for the picture is a sign of disrespect for the teacher. Although he has internalized In Hun’s words and views, he is so affected that he no longer admires In Hun like before. In the chapter 42, he no longer calls Jung In Hun “learned sir” but “my teacher” which illustrates that BNK no longer views IH as a noble (“sir”) but as a simple teacher. He only sees Jung In Hun in his actual position and not as his social status. We all know that despite being a noble, JIH is not rich and influential. He belongs to the lower nobility. IH is no longer put on a pedestal. But BNK has still some respect for IH as he calls him “my teacher”. So there is still a string between the teacher and the painter but it is about to disappear. 
, here his tears are linked pain and sorrow, as the artist is heartbroken. 
(chapter 42) This time, it is the lord who initiates the embrace, something the painter had been longing. 
(chapter 41) Yet, this request only got fulfilled at the end of the love-sex session, the main lead put the painter on his lap while kissing him and even embraced him in an desperate attempt to console the artist. Simultaneously, this shows that Seungho is longing for warmth, love and tenderness. But despite this night, Seungho is well aware that Baek Na-Kyum is not loving him. He has sex with him because BNK has confessed before that he has never hated the things he did with Seungho which represents a huge step for the lord. 
(chapter 38) Striking is that the painter blamed himself. From my point of view, the painter’s confession could only wound the noble’s heart. 
(chapter 41) He had the impression that he was somehow responsible for the artist’s tears. Yet after this night, Yoon Seungho had sensed that something had changed in their relationship, just like Baek Na-Kyum’s relationship with the teacher had changed. Notice that this room is connected to betrayal, love, sex and pain.
