In the midst of intense jealousy and repression, Ma Wen resorted to all kinds of tricks to disturb their lives, inadvertently leading to a series of comedic situations. Out of desperation, Li Yi began to introduce Ma Wen to potential partners, trying to use new love to push Ma Wen out of the house. After repeated failures at blind dates, Li Yi introduced his own sister, Li Qin, to Ma Wen. Unexpectedly, Li Qin developed genuine feelings for Ma Wen, and he gradually regains his confidence as a man through her. Just as Ma Wen finally finds a new love, Yang Xin discovers that her feelings for him have rekindled... One is his ex-wife who once betrayed him, and the other is a lovestruck rich woman who fell for him at first sight; what choice should Ma Wen make between Yang Xin and Li Qin? On one side is a former husband who is down on his luck, and on the other is a remarried husband who puts on a brave face. Can the lonely Yang Xin seize her own happiness?
