On her engagement day, jewelry designer Avery caught her fiancé cheating with her stepsister. She canceled the wedding on the spot, walked up to Adrian (her ex-fiancé's boss), and boldly asked him to be her "temporary replacement groom." Adrian agreed publicly and gave her seven days to make a clear-headed choice. A week later, Avery chose to marry him. Afterward, she not only fought back against her ex's workplace sabotage and reclaimed credit for her project, but also exposed her stepsister for stealing her late mother's designs and forging certificates. In the end, Avery achieved career vindication at her solo jewelry exhibition and confirmed a mutual, true love with Adrian.
