Ryou possesses the largest breasts of any shoujo manga heroine to date! However, life is no piece of (cheese) cake, as she is constantly harassed by perverts eager to grope her. The first man who does not obsess over her assets happens to be the first man she actually wants to obsess over her, although there is something odd about him... At one moment, when she is with him, he is a sweet masochist; the next, he is a bold sadist. Which does Ryou prefer? The S or the M? She must make a choice, because it turns out she CANNOT have both. Discover the surprising reason why one face has two personalities! Included one-shots: Volume 1: Gattsuiteke! (It's Unintentional!) Volume 2: Natsu no Ouji-sama (Prince of Summer) Volume 3: Shiitake. (The Mushroom Girl)
