Won-hee, the hospital's newest nurse, shows an interest in Yeon-woo, but he doesn't appreciate her advances - he doesn't even get along with hospital colleagues he's known for years. Through a few chance encounters, they gradually grow closer and he opens up his heart to her. However, Won-hee has a secret that she hasn't told Yeon-woo, and it appears that their love will never be.
