Because the rain was falling, it was okay. Because the rain was falling, I couldn't see your tears.

Choi SaeJi is an independent young woman who has been engaged to the perfect guy for over a year. But when the big day arrives, SaeJi is no longer who she used to be. Now she's just someone who was left at the alter by her fiance Park Junghwa. Torn to pieces on the inside, she runs outside of the church in her flowing wedding dress only to get herself into an even bigger situation. In her rage, SaeJi practically faints when a car stops just short of her in the pouring rain. The driver--Kim Key, a handsome business man and a complete stranger to SaeJi. Key is now more than just a stranger but someone that will help SaeJi back on her feet again and back on the road to happiness.
