On the day of the wedding, female protagonist Lin Wantang pushed open the bridal lounge, only to find her fiancé Zhou Jingchuan personally helping his first love adjust her veil, and what his first love was wearing turned out to be her wedding dress! To make matters worse, her future mother-in-law not only backed up the first love but also told Wantang to go do her makeup in the utility room. Seven years of relationship, traded for such humiliation! Lin Wantang called off the wedding on the spot, but unexpectedly uncovered an even bigger secret: while she had painstakingly paid out of pocket for the wedding banquet expenses, Zhou Jingchuan had secretly used her money to support his first love and repay old debts. Faced with the calculations and moral blackmail of the man's family, Lin Wantang refused to back down any longer.
