On the road of youth, he met girls with different personalities such as Xiao Jin, Tang Song, Qin Weiwei, He Mengsha, etc. Some of them moved their heads, some moved their hearts, and some were just passing by. Until one day he encountered separation, and the gap in his heart was gradually torn apart... If you can't see it, don't think about it, don't doubt it, and don't misunderstand it. There is a kind of love where we circle around the center of each other's circle, but in the end we never get out of our own circle.
