Sora no Seibun(1997)

Okamoto is a basketball player who has came to this high school just to be with his girlfriend, Yumi.



Yumi has a large ugly scar on her back from when Okamoto accidentally dropped a boiling kettle on her when they were kids. Since then, Yumi has made Okamoto take responsibility for the accident by forcing him to stay with her.



All that changes when the short and skinny Koizumi joins the basketball club. Koizumi is so effeminate that you can't even tell whether he is male or female in casual clothing.
