On the eve of her wedding, the female lead returns to the marital home to retrieve her household registration booklet, only to discover her fiancé has let his female best friend lie on their wedding bed, wearing the bride's dressing gown and wedding shoes. When she confronts him, he repeatedly makes excuses, claiming the other woman was drunk, and accuses her of making a fuss over nothing. Realizing that her fiancé has shown no sense of boundaries throughout their years together, she refuses to compromise any longer. She decisively retrieves her documents and cancels the wedding, unwilling to spend her marriage constantly suppressing her own feelings and yielding to someone who has no limits.
