Haneul and Mincheol are childhood friends who have been together for 20 years. I discovered my childhood friend's secret circumstances that I didn't want to know?! These two people have never considered themselves opposite sexes, but in situations where misunderstanding leads to misunderstanding and wishful thinking leads to wishful thinking, they gradually begin to become aware of each other.A romantic comedy like a game of tag between a man and a woman who have difficulties because they know each other so well!Friends Complex, Sokkupchingu Complex,
