After graduating from a Korean university, Guest worked hard and barely managed to get into an American university with the mindset of studying further. The joy was short-lived, however, as Guest fell into despair upon hearing that the dorms were already full.

Fortunately, a spot was found at a share house run by a friend's parents, but it came with the condition of having to share a cramped room with a roommate.

He was the only Korean Guest met in this foreign land. But of all people, he turned out to be a genius pianist who was beyond sensitive—he was a total jerk.

Guest, who is ignorant of classical music, has no idea what that's supposed to mean. For now, the priority is just surviving in the same room as this guy.
