High school is difficult for most kids. But for Kayano, a shy girl whose single mother seems to work all the time, it's even worse than usual. She's so afraid of drawing attention to herself that she can't tell the handsome Kamijo how much she loves him until one day she finally gets up the courage to write him a letter confessing her feelings. When she goes to give him the letter all her plans go awry. She's given the letter to the wrong person! Accidentally, she's given her love letter to Takeru Edogawa who just so happens to be the school principal's son, head of the delinquents and the notorious "Prince of Attraction"! To Kayano, he seems like Satan himself. Not only is he devilishly handsome, but he seems to take the utmost pleasure in making her suffer. Things only get more interesting when Kayano's mother comes home one day and announces she's getting married again --- To principal Edogawa! What will Kayano do when she has to live with this devil 24/7? How will she cope with her literal "Hell on Earth"?
