When Ao Horie's handsome classmate confesses his love to her, she finds she can't stop thinking dirty thoughts about him.

When Ao was in kindergarten, she smiled ear-to-ear as she told her classmates how her father (a bestselling erotic author) chose her name: "A as in apple and O as in orgy!" That day still haunts her ten years later as she studies with a single goal in mind: get into an elite university and achieve independence from her father once and for all. She has no youth to misspend and no time to think about boys - until her classmate, "King Normie" Kijima, approaches her with a shocking confession of love. She tries to lose Kijima, but he just can't take a hint - and as her mind runs wild with impure thoughts, she realizes her father has totally influenced her.
