On the fifth wedding anniversary of his wife Lin Yimi, 32-year-old financial risk controller Chen Ji accidentally discovered the fact that his wife had brought a third party home with him. Faced with his wife's excuses, moral kidnappings and hysterical attempts to redeem her, he, who had always been calm and rational, stuck to the bottom line and decisively filed for divorce. Even though he later encountered repeated entanglements between his wife and a third party, and the woman turned around and sought reconciliation after the two fell out, Chen Ji was always clear-headed and cut her losses, finally letting go of the unbearable five-year marriage, bidding farewell to the past, and starting a new life of her own.
