About the title
Sun-woo is a cold-blooded perfectionist who runs an expensive restaurant. He handles his work so masterfully that he has earned the boundless trust of his boss, Kang. Mr. Kang has a problem — it seems his young girlfriend Hee-soo is seeing someone else on the side. Kang trusts only Sun-woo with this matter and orders him to kill the girl if the suspicions turn out to be true.
