This is a concise story, so concise that it ends before Cheng Xia realizes how important Guo Kai's existence is. Life is like a white horse passing by, and people are in a hurry. Can you still be as pure and impulsive as you were when you were young, holding on to all the love and not letting people go away, and everything is already the end?
Concept: Cheng Xia's ordinaryness and Guo Kai's fragile heart are destined not to be together. Will there be any point in waiting?
