Lu Chenzhou, returning from a business trip, discovers his wife Su Wanqing and male best friend Zhou Ziang sleeping in their marital bed, turning seven years of dedication into chips for others to squander. He dismantles the bed, sells the house, demands back the money, resolutely ends the marriage, and restarts his long-shelved entrepreneurial plan. When his ex-wife sees through the scam and begs tearfully for reconciliation, he has already broken through shoulder to shoulder with investor Shen Qinghe, moving from business partners to life partners. A betrayal teaches him to cut his losses in time and finally finds for himself true love with mutual respect and shared responsibility.
