Cha Soo Hyun has already decided to break up with KJH, nevertheless the latter is unaware of her decision. Since she knows that a bad break up can be really painful due to her husband’s fake affair, she decided to leave a good memory behind believing that this would lessen the pain. And we all know that no matter how you break up, the pain will never be lessened.
She thinks that she should break up, just like her ex-husband did, for the same exact reason: protection. She wants to protect KJH and his family.
Since KJH had proposed as a date to visit a book store together where they could read books together and exchange their favorite book, CSH thought, she needed to grant his wish. She knew that this would be his favorite date, the perfect date. Our heroine chose as book Alice in Wonderland and KJH The little Prince. Yet, the perfect date ended here.

I chose this taking because it perfectly fits the situation. Their future separation is illustrated in this scene. The counter serves as border, just like the decoration with the books on the ceiling. Moreover, CSH is standing far away from KJH reinforcing this impression that CSH has returned to her own world. The distance between them in this taking illustrates the inner distance CSH created. Then you can distinguish an invisible frame in this picture, it really looks like there is a glass or a window between them. And this invisible frame corresponds to the invisible change in CSH. CSH has not just started to put a boundary between herself and KJH but also put a gap between them and KJH is unaware of it. She doesn’t share her thoughts and feelings any longer. She is actually hiding behind her smile that’s why KJH is so happy. He said once that seeing her smile would make his day. So he thinks, CSH is happy. Striking is that CSH has adopted KJH’s mannerism. The latter did the same in the past. He never wanted people around him to worry and burden them hence he smiled a lot. The illusion is perfect: she smiles, they spent a good time together so for him, everything is perfect. Yet, she is about to hurt him terribly because he is not expecting it.
Strangely, while KJH is waiting at the counter, he waves to her.

His gesture means for him (Here I am, look at me!), however for CSH it means the opposite: waving goodbye. Remember that she wanted to break up at the end of this perfect date but she couldn’t as KJH offered her a gift: the camera case with her name on it. That’s why she had to postpone it and find the right time. She came to the conclusion that the timing is as important as the way of parting. yet, she is making a huge mistake because no matter how and when, breaking up is really painful.
Yet, there is one thing that caught my attention: she is wearing a red coat. First red is her favorite color (see the dress in Cuba) but she is showing her love for KJH by wearing such a color. She is even catching people’s attention with her coat. She wants the attention from the media on her so that she can quietly break up with KJH without causing any wave. So loving KJH has definitely changed her. She might put an invisible distance and boundary between herself and her boyfriend, yet she is not giving up on her love. She has decided to love KJH but from a distance… so her love will remain despite the break up. As you can see, KJH’s words and behavior have influenced her greatly, she is a changed woman, although there is still something that KJH couldn’t change: her insecurities and fears, the last wall he couldn’t tear apart. She still views herself as cursed, her relationship with KJH was just a dream because it was too wonderful to be true.
