Jin Woo doesn't want a roommate—or to fall for one. But Ki Sub moves in anyway, turning quiet disdain into something far more complicated.

Jin-woo is new to romance, so he dreams of the best partner. Then Gi-seop, tall and good-looking but shallow, gets Jin-woo's attention. Jin-woo thinks Gi-seop is never enough for him, but at the same time, he can’t stop thinking about him. As Gi-seop is used to being the one asked out and always saying yes he wonders why Jin-woo does not make a move. But then it hits him: Jin-woo's standards are sky-high. So, he decides to move in to Jin-woo's house. Living together, they keep bumping into each other and one accidental kiss stirs them up.
