Plot Summary: A Second Chance at Revenge and Romance

On what should be the happiest day of her life, Yerin experiences the ultimate betrayal—her fiancé and best friend turn against her on her wedding day, and she loses her life in the aftermath. But fate offers her an extraordinary gift: the chance to go back in time to the moment of the proposal. With newfound knowledge of their treachery, Yerin embarks on a calculated plan to bring her ex-fiancé and former best friend together, orchestrating their downfall as an act of revenge.

However, as her revenge plot unfolds, Yerin's heart begins to soften. The one man she once rejected—the only one who truly loved her—becomes increasingly important to her.
