Five years ago, one misunderstanding tore them apart. Now, fate has brought them back together. Y/N thought she had moved on. She had built a new life in the U.S., far away from the memories of the love she lost. But when her job forces her to return to Seoul, she finds herself back in the same city as Taehyung-the man who once held her heart, and the man who now looks at her with nothing but coldness and resentment. Taehyung was once Y/N's best friend, her everything, until one night shattered their trust and left him believing she had betrayed him. Now engaged to another woman, he should be happy, but seeing Y/N again has stirred up old feelings he thought he had buried. As they navigate family gatherings, jealousy, and the unresolved tension between them, Y/N and Taehyung must confront the truth of their past and the feelings that still burn between them. Can love survive betrayal? Or will the fire between them consume everything they once had? A story of second chances, heartbreak, and the undeniable pull of love that refuses to fade.
