Yeon-woo's Father
In a tranquil countryside hospital, radiologic technician Yeon-woo suffers from a mental disorder, the result of a childhood trauma in which he witnessed his younger brother die in a car accident. 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.
Mr. Park
Kim Sun-woo is an enforcer and manager for a hotel owned by a cold, calculative crime boss, Kang who assigns Sun-woo to a simple errand while he is away on a business trip; to shadow his young mistress, Hee-soo, for fear that she may be cheating on him with a younger man with the mandate that he must kill them both if he discovers their affair.
