But she'll need money to care for him, and in a town where the highest of the high are neighborhoods separate from those who are striving just to make ends meet, that's no easy task. Due to her boyish looks, her friend helps her cross-dress to get a job at a host club (of sorts), but when her first interaction goes horribly wrong, she think's it's all over for her...until über-rich boy Tohma saves her. Amused by her story, he makes her an offer she can't resist: Serve as his male" butler until March of next year, and he'll give her $10,000...but only if her true gender isn't revealed!"

However, as exposure therapy for his allergy to women, Tohma transfers to her school and even rents out the second floor of her house! And when Haruki finds out, it's a heart-pounding First Ward reunion in Rui's tiny apartment! Can Rui survive the attention of three guys at once? Does the thrilling life of a cross-dressing butler never end?!
