I demand absolute obedience.” Yu Akabane has worked hard to reinvent herself for high school, and there’s only one step left in her plan to leave her plain Jane days behind: asking out her idol, the “White Prince” Shirakawa-kun. When circumstances lead to Yu moving into the school dorm where Shirakawa-kun boards, she thinks she’s found her lucky break. But unluckily for Yu, “Black Devil” Kurosaki-kun, the boy everyone at school (including the teachers!) is afraid of, lives there too-and when Yu defies him, he’s all too eager to punish her...
Yu and Kurosaki-kun have started going out—on the condition that she “learns to obey him.” Brought down by her new boyfriend’s no-holds-barred training, Yu is, for once, doing as she’s told. When she stops clashing with Kurosaki-kun, she sees a new side of him, and just in time for their first Valentine’s Day to arrive. Yu is nervous, but come on, even crabby Kurosaki-kun has to accept chocolate from his girlfriend! If she can force her way through the crowds of the princes’ admirers to get it to him, anyway… Will Yu’s Valentine’s Day turn out to be sweet, or bitter? Plus, a new school year will be bringing changes to the dorm, too…
