Lu Yiyi, who has lived abroad for seven years, decided to leave this place where she had nothing and return to China to develop anew in order to escape the pain of a broken relationship.
But for some reason, when she reunited with her old friends from high school, she felt very strange to them. Even if she searched for memories in her mind, there seemed to be an invisible barrier blocking her memories.
While she was still in a state of confusion, she accidentally met her ex-boyfriend in high school, Hu Ruiming, and now he was tall and handsome, with such a warm and jade-like smile, Lu Yiyi almost became a nymphomaniac looking at him. But the most fatal thing is that Lu Yiyi has no memory of him at all.
In this state of half-knowledge, Lu Yiyi inexplicably returned to her high school days. Having lost her memory, she had been acting cautiously in order not to let others notice her strangeness.
But when she met Hu Ruiming in high school again, it seemed like they didn't know each other, but the ambiguity between them puzzled her! This made her already a mess even more confused.
She was still trying to find a way to go back, but she slowly fell into her high school life. A series of experiences made her start to recall all kinds of happy, sad, and sad things.
Concept: The heroine inexplicably returns to high school and falls in love with her ex again
