Hyun Woo (Yoo Ji Tae), a law student, and Min Joo (Kim Ji Soo), a television director, are very much in love. Engagement takes the love to a whole new level. Hyun Woo tells Min Joo to wait at the cafe on the groundfloor of the mall. As Min Joo waits, the mall collapses with her trapped inside. A few years later, the broken prosecutor Hyun Woo receives a journal with Min Joo's handwriting, showing where to go on their honeymoon. While traveling, Hyun Woo meets Se Jin (Eom Ji Won) that seems to be traveling the same way he is. Coincidence?
