A girl named Lu Xiaoxi has a brother who loves her, and they have a good father. But they will grow up and dad will get older.
The little girl always believed that there would be someone who would risk everything for her, but as time passed, she discovered that it was not what she imagined. There is no man in this world who will wait for you forever. You can be in his heart for a lifetime, but the person who stays with him for a lifetime is not you.
Du Yining is the person Lu Xiaoxi identifies. They have a beautiful past and will have a tangled future. In this way, they squander their youth, but what they get in exchange is a lifetime of longing...
If missing is also a kind of beauty, then why bother to forget it deliberately?
