Kaoru is a 17-year-old virgin who has an S&M fetish. He has always dreamt about an SM relationship with his childhood friend Nana, who is looked upon as perfect and is always the target of boys' eyes. Their relationship has somewhat deteriorated through the years, due to them hanging out with different people and because Kaoru is not taking his education too seriously. One day though, Kaoru's mother gives some of his S&M toys to Nana for safekeeping. Nana finds the leather one-piece that Kaoru bought and tries it on but accidentally locks herself in it and doesn't have the key! Kaoru frees her of the one-piece, but then Nana realizes she may like Kaoru's hobby more than she thought. Subsequently, the two of them start engaging in so-called "breathers." These breathers are intended to relieve Nana of stress that originates from her attempts at keeping her grades and name perfect.

Timid Ooyama keeps to himself at school, and he certainly never gets involved with Akutsu Riko, a delinquent as buxom as she is notorious. But when she turns up at his apartment out of the blue, what’s he supposed to do, kick her out? She’s gorgeous! And scary! But things get complicated when Akutsu asks to stay the night, then starts turning up over and over again after school–reading Ooyama’s manga, sprawling out on his bed, and digging up his smut stash. Why exactly is she claiming his life as her hangout?! She makes it clear there’s no way she could possibly like him, but the teasing threatens to boil over into something more in this sexy yet adorable slice-of-life rom-com!
