Woo-Jin is a man who turns into a different person every morning when he wakes up, while there's a woman, Yi-Soo, who's in love with him. What would you do if you woke up with a new face every day? Woo-jin, a man who designs furniture for a living, is used to this. An elderly man, a little boy, a chubby woman, a foreigner, Woo-jin has grown accustomed to his super-natural “situation.” The only people that know of his illness are his mother and his best friend Sang-baek. One day, he meets Yi-su, a girl who works for a furniture store, and instantly falls in love with her. Since his physical identity changes frequently, he continues to visit her daily, acting as a customer that she has never seen before. Woo-jin finally musters up the courage to talk to her and ask her out on a date. The perfect date passes by and Woo-jin, knowing that his face will change once he falls asleep, attempts to stay awake for as long as he can. He meets Yi-su for three consecutive days and Yi-su also falls in love with him. However, Woo-jin can no longer fight sleep. He passes out and wakes up with a new face. Will Woo-jin tell Yi-su about his condition? What will Yi-su think?
