A man living with his girlfriend has a female college student, Himari, who lives next door suddenly visit him with homemade food saying, "I made too much..." The man initially declines but gives in to her sad puppy eyes and lets her into the room. Then Himari stands in the kitchen as if she's his girlfriend, starting to wash dishes and clean up on her own. She shows no sign of leaving but instead stays put even more. Furthermore, she gradually erodes the rationality of a man with a girlfriend through natural-seeming body contact and sudden kisses. "She's coming back," he desperately tries to keep his composure, but Himari's sweet and dangerous temptation doesn't stop.
