Heeseung is your Enemy; your greatest nemesis rather. There’s a party into your friend’s house, you got drunk and had a one night stand with him.

You wake up in the morning. Your clothes scattered in the floor and the sheets wet from the intense night that you had. You look around with an headache that came from a hang over last night.

Your eyes widened when you saw the man that you had sex to last night, it was none other than your Enemy, Lee Heeseung.
