Four high-school bishōnen, Kyohei Takano, Takenaga Oda, Yukinojo Toyama, and Ranmaru Morii, have made a deal with their landlady, Mine Nakahara: if they succeeded in transforming her niece into a proper lady they can live in their home rent free, but if they fail the rent will triple. The niece, Sunako Nakahara, is poorly dressed with bad skin and no fashion sense whose bangs cover her eyes. She is also a heartbroken horror-fan who has spent two years as a hikikomori after being told she was ugly when she confessed to her middle-school crush.

The boys try to cut Sunako's bangs, with no success. After Sunako accidentally walks in on Kyohei bathing, he jumps out of the window in surprise and catches a cold as a result. They do not know this until Sunako has to defend herself against a gang of ganguro females, dressed in kogal fashion, as they try to cut off her bangs by force, due to their jealousy of her familiarity with Kyohei. Eventually, Kyohei saves Sunako, however ends up with a fever. Sunako has to take care of him which she does not approve of, debating whether or not to kill him. As she attempts to, the other three boys walk in, and a black hole forms, pulling them in.

Four men of the Japanese host scene try to forcefully recruit Kyohei. Sunako doesn't think she can survive living around a bishōnen like Kyohei, as she plans to kill him. However, she has to save Kyohei from the recruiters who have kidnapped him for dubious purposes. Mine returns to invite everyone to a coming out party for Sunako, by which the boys have to make Sunako a lady as soon as possible.

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.

A picture of an angry Sunako from the festival catches the eye of an egotistic photographer who wants her to model for him. Although tricked into going to the shoot, a camera-shy Sunako proves a difficult subject. The four bishōnen are soon dragged into replacing Sunako in the modelling shoot, however they take leave with Sunako after the photographer explains the difficulty shooting Sunako. The five of them later go an exhibition of where a picture was discreetly taken of them, as it turns out that the photographer used that picture as the greatest attraction in the exhibition.
