Most people should be very disappointed with the ending, but I personally think the ending is a bit unexpected and reasonable. It was unexpected because the relationship between the two of them was very good until the middle part of the last episode of the show, and no one would have thought that they would break up. As a result, the director did a 360-degree turn and made the two break up! Yes, this is indeed a break from the usual formula of happy endings in campus Korean dramas. It is reasonable to say that it is because of Liu Zheng's character weakness that the person who ultimately hurt Xiaoxue was Liu Zheng. Liu Zheng knew this very well. It was precisely because he realized that he would hurt Xiaoxue that he chose to separate. Perhaps this was another way to protect Xiaoxue. The ending puzzled many viewers. I think one of the reasons may be Liu Zheng’s strange and incomprehensible character.
The ending disappointed many people, probably because the director did not give the audience a happy ending, but left the show with regrets. I personally think that the director left a lot of room for imagination for the audience, and it ended abruptly in the middle, which is indeed a bit unpleasant. But I think the director actually left a lot of foreshadowing of Xiaoxue and Liu Zhenghui's reconciliation, such as Xiaoxue's relationship with her senior After the breakup, they never fell in love again. For example, Xiaoxue has been leaving messages to her senior since her senior left. In the end, the play ended with the senior reading Xiaoxue's message, and the two passed each other on the road, and Xiaoxue looked back, etc. I think this is a hint that the two will still be together.
