When high school girl Hatsumi has to go buy a pregnancy test because her popular sister Akane is 'late,' who does she run into but her creepy bully neighbour Ryoki. And now he's blackmailing her to become his slave! How will mild-mannered Hatsumi get out of this mess? Will Hatsumi's childhood crush (and male model) Azusa be able to save her from Ryoki's clutches?

Our heroine Hatsumi is on Cloud 9 when male model and childhood buddy Azusa asks her to be his girlfriend, but all is not as well as it seems: Hatsumi still has to get out from under the creepy clutches of her 'master' Ryoki, who insists on continuing to blackmail her. In addition, on the night of her first date with Azusa, Hatsumi's dad intervenes and grounds her. But that may not be the worst of it for poor Hatsumi, because something's brewing with Azusa, and her knight in shining armour may not be what he seems.
