Kazuya is an orphan. He was raised by his older brother, Kazuhiro, who attended Ryokuto academy. Hasukawa idolized his brother and wanted to enroll at Ryokuto to be more like him. At the start of the series, we see him enrolling into the school, realizing his dream, but he is very late due to a series of freak accidents. To make matters worse, Kazuhiro has just married Kazuya's first love, Sumire! Unable to live in the same house as the newly-weds, Kazuya moves into the dorms. Little does he know what terrors await him there! 

Hasukawa Kazuya is in a terrible bind. His brother's new wife is also the woman that Kazuya secretly loves. Determined to avoid them both, Kazuya leaves home to live in the student dorm called Greenwood. There, he hopes to find peace of mind. Unfortunately for Kazuya, stability and peace are the last things one might find at Greenwood - home of the weirdest characters on campus.

It seems like 15-year-old Kazuya Hasukawa's life can't get much worse. Not only did his older brother marry Kazuya's first love, he brought his bride home to live with the family! Forced out of his own home, Kazuya enters an exclusive all-male boarding school, Ryokuto Academy. Unfortunately, a prestigious education is little compensation for getting stuck with the cross-dressing roommate from Hell...
