本片根据网络小说《和空姐同居的日子》改编。
A game and graphics designer lives and works alone in his apartment. One night, he finds a drunken flight attendant passed out at his front door and puts her up for the evening in his apartment. It soon becomes apparent that the flight attendant has been recently evicted from her apartment in the same building, and with nowhere else to go, she decides she's going to move into his place whether he likes it or not. He's used to being alone, and she's very outgoing...can these two polar opposites co-exist together, and can their living arrangement result in something more than just being friends and roommates?
