To end five years of long-distance dating, Lin Zhou quits his million-yuan-a-year job and heads to Xia Qing with 300,000 yuan for a down payment. But when he gets home, he finds her caring for her feverish close male friend, who is wearing their promise ring. When Lin confronts her, Xia mocks him for being incapable. He demands his down payment back on the spot and returns to Shenzhen that night. She thinks he will eventually come back and beg to reconcile, unaware that he has regained the peak of his career and met Su Wan, who truly understands respect and boundaries. Only when her male friend swindles her out of money does Xia see his true colors and bitterly regret her choices. On his wedding day, she tearfully begs Lin to take her back, but he says only, “I once loved you, but today, my wedding has nothing to do with you.”
