There is no right or wrong love between Shu Che and Miao Ying. Shu Che can understand Miao Ying's helplessness and grievance, but he can't turn a blind eye to the transaction between the two families. Their love is over.

For the breakup book, Chu Che is reluctant to give up.

Many people may think that the six-year relationship between Shu Che and Miao Ying is too decisive, but it is not. His heart is even more reluctant to give up, and he doesn't want Miao Ying to be hurt more. Sometimes, the best love is not being together, but letting go. Shu Che said:

"I broke up with her, at least she didn't have to do what she didn't want to do in the future, and she didn't have to be sandwiched between her father and me and torn on both sides. She doesn't have to endure that whatever she does is wrong and unfair. If she is with me, it will always be endless grievances, worries and even fears. I would rather have a long pain than a short pain. "
