Yoshida is an ordinary guy who was rejected hard by the woman he'd spent the last 5 years having a crush on. On his way home after getting drunk at a bar, he finds a teenage girl crouched on the side of the road... "If you let me stay at your place, you can sleep with me." "You shouldn't say that, even as a joke." "Then let me stay over for free." Before he knows it, the girl, Sayu, has moved in with him. This is the story of a runaway teen girl and an ordinary 26-year old man.
