Woo Soo-han is what you would call the “complete package.” He’s young, physically fit, handsome, and has flourishing career to boot. He’s got everything anyone could ever desire, except maybe a relationship. That never bothered him, as work has always been his main priority. Everything changes when he meets his close hyung (and work subordinate)'s wife, Nayoung. From the moment he laid eyes on her, he felt an inexplicable attraction. Soo-han knew it was wrong and tried to forget about her but when the two cross paths at a night club, and he ends up taking an intoxicated Nayoung back to her house. After discovering her husband isn't home, Soo-han finds that he is no longer able to control his urges..
