18-Year-old Lin Zhiyi is a strong academic who firmly believes that "reading is more reliable than falling in love". The 20-year-old Gu Yanzhi is a cold-faced scholar who bears the expectations of his family and a heavy past. An accident of "contracted couple" forced their life trajectories to intersect. From the "acting competition" that they didn't like each other, to the unknowing revelation of their true feelings, they left the deepest mark on each other's world. However, when the sweetness reaches its peak, the secrets of the past and the obstacles of reality emerge like icebergs, and a helpless separation is caught off guard. But what they don't know is that all the short separations are for the purpose of embracing each other tightly again in a better future.
