Sunako's class recruits her to make a haunted house for the school festival, only for Kyohei to realize that she was conned by the class president. Kyohei recruits the guys to help make her haunted house win the contest of the school festival so he can get the prize. They ultimately win the contest, however Kyohei is left to claim the prize, since the other three refused to accept it. Unfortunately, Kyohei is forced to pay for the damages caused by the explosion inflicted earlier.
It's a gorgeous, spacious mansion, and four handsome, fifteen-year-old friends are allowed to live in it for free! There's only one condition—that within three years the guys must transform the owner's wallflower niece into a lady befitting the palace in which they all live! How hard can it be? Enter Sunako Nakahara, the agoraphobic, horror-movie-loving, pockmark-faced, frizzy-haired, fashion-illiterate recluse who tends to break into explosive nosebleeds whenever she sees anyone attractive. This project is going to take more than our four heroes ever expected: it needs a miracle!
