After she turns him down, he decides to let go of the past and start a new life at Donghai University. At the train station, he unexpectedly meets Xia Wenyan, a beautiful, aloof senior admired across campus, and through a series of misunderstandings, they end up becoming roommates in a shared apartment. As they spend time together, Li Xingmo's sincerity and thoughtfulness gradually melt Xia Wenyan's icy exterior, allowing her to experience warmth despite the shadow of a family that favors sons over daughters.
