A woman reincarnates as a side character destined to die after marrying the story's hidden antagonist. To avoid her fate, she tries everything—proposing to others, running away, and defying expectations. But her efforts only bring her closer to the original plot. When the antagonist unexpectedly proposes, she must fight to survive, find love, and rewrite her doomed ending. The more she tries to change the story, the more it pulls her back.
