After receiving a letter from Miss Seukhye about her not returning to Zitao’s life anymore, he understood why the other did it. It’s for the best for the both of them. You can’t blame her from leaving because it’s Zitao’s fault as well. He has been pushing her away from him since she returned for the fourth time. Why? Because he doesn’t want to be hurt again. He had placed a line between them. It’s not the same as before when they walk around hand in hand and place kiss to each other’s lips. Zitao limited himself from touching her or even talking to her. He was always stopping himself from having physical contact with her because he knew that he can’t stop if he do that. It was hard but Zitao did it for the both of them. He didn’t tell these things to Seukhye because he knew that it will hurt her and Zitao as well.
