Despite the Zhou family's parents making things difficult for her and the return of Lin Wei, his ideal first love, she remains clear-headed and carefully plans her escape. When the contract finally expires, she settles every account and leaves without hesitation, opening a small flower shop. Only after losing her does Zhou Qisi finally realize his mistakes. He puts aside his pride and pursues her, and in the end, the two sign a new romantic relationship contract as equals.
