The night before the wedding, to save her family business, Xu Ning temporarily replaced Jiang Yu, her prospective groom of four years, with Qin Yue, who could bring financial commitments. It wasn't until after the wedding that she discovered Jiang Yu had been secretly supporting the Xu family all these years. Lacking special care, Xu Ning began to face operational difficulties alone, and she also re-examined the boundaries of marriage, interests, and affection. Three years later, she relied on herself to help the Xu family stand firm, and finally gained the qualification to face Jiang Yu and that unfinished affection once again.
