Freshman Su Nianxing got lost in school and mistakenly splashed the white shirt of senior computer science student Lu Zhiye, starting a happy first encounter with enemies.

They achieved each other in their youth and moved from a green campus to a pure and sweet love that they will stay with for the rest of their lives.
