On her eighteenth birthday, Li Weixiao rescues a guy named Ji Yanchen. He says he’s lost his memory and can’t find his way home, then clings to Li Weixiao and refuses to leave. Weixiao finds him incredibly strange: he’s cool and quiet, yet curious about everything. He seems to know how to do everything, but has no common sense about everyday life! He’s such a walking contradiction... It’s not until one dark and stormy night, when a strange wind sweeps her away to a place she’d never even dare dream of, that she discovers the enormous secret this man has been hiding...
