A man living in an apartment posts an online ad looking for a roommate, and to his delight, Anna Anjo, a stunning quarter-Japanese beauty he once saw on TV, applies. Excited, he begins secretly filming her naked body through a crack in the bathroom. When Anna discovers his voyeurism, she confronts him—not only demanding he stop taking pictures, but blackmails him into letting her stay rent-free in exchange for allowing him to touch her. Unable to resist her seduction, he gives in, and soon finds himself indulging in a sweet, dreamlike cohabitation—fondling her breasts, receiving passionate tongue kisses, and falling into an erotic relationship beyond his wildest fantasies.
