Erotic manga artist newcomer, Miaku Chiru, has a crush on her editor, Minami. She wants to make a move on him, so she tries using roundabout ways to seduce him, but he's always got his guard up. That won't stop her, as she's just reckless enough to bust through his barriers to get what she wants. What could stop her, though, is a potential challenger for Minami's heart: the beautiful and busty editor, Sena, whose mature aura makes Miaku feel like an amateur. In the battle for Minami's heart, who will win and who will leave in heartbreak?
