Lin Wanwan, a freshman from an ordinary family and introverted personality, entered Nancheng University with a literary dream. On the first day of school, she accidentally broke into the private studio of the campus male idol Gu Yanshen and accidentally trampled on one of his paintings that was about to be exhibited. From then on, a ridiculous and sweet story began.
Gu Yanshen - a genius senior student in the Department of Architectural Design and the son of the school director, he is cold and taciturn but has a gentle heart. He discovered that his long-lost childhood Bai Yueguang was actually the panicked elementary school girl in front of him. The handwritten love letter from the little girl seven years ago that he had always treasured was exactly the same as Lin Wanwan's handwriting...
"I haven't forgotten a word of the love letter you wrote to me seven years ago."
"Gu Yanshen, have you liked me since your freshman year?" "No, seven years ago."
"I never thought I would fall in love with anyone until I met you - it turns out that waiting makes sense."
Lin Wanwan: "When did you start liking me?" Gu Yanshen: "Probably... The day you trampled on my painting." "Don't you hate me very much?" "I hate you so much that I only remember you."
