On her first day after transferring schools, Jiang Qiao runs into Xu Si, the most untouchable boy in the entire school. A sweet, gentle top student meets a prickly young man. One is hiding a serious illness, while the other is wrapped in old wounds. During that long midsummer, two wounded souls unexpectedly become each other's only light. "Xu Si, if one day I disappear..." "I'll come looking for you, until I find you." But he doesn't know that his little rose had already hidden the secret of her fading away that summer. Youth is too short, and the rest of life is too long. The only thing she has never regretted is loving you.
