The story revolves around Lin Wanxing, a girl who hides her inner trauma with a bright smile, and Jiang Chen, a boy who is indifferent and alienated due to the shackles of his family. A "fake" sadomasochism that started as a campus conspiracy eventually became a true story of two people redeeming each other, tearing apart each other's darkness and illuminating each other's world. This is not only about love, but also a growth epic about self-identity, courage and independence.
