The Wallflowers

Four high-school good-looking boys, 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; her bangs cover her eyes. She is also a heartbroken horror-fan who has spent two years as a recluse 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 group of ganguro girls who try to cut off her bangs by force, due to their jealousy of her familiarity with Kyohei. Eventually, Kyohei saves Sunako, but he 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. The episode ends with Sunako screaming possession over Kyohei.

Four men of the Japanese host club 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

When Sunako becomes ill, the four bishōnen is left with a household of chores. They unsuccessfully attempt to clean, by which they figure out, with the help of Noi, that Sunako misses Halloween, being her favorite holiday. They later throw a Halloween party to cheer her up.

A leader of a gang falls in love with Sunako. Thinking that Kyohei is his rival, the leader of the gang challenges him to a fight declaring who deserves Sunako as their lover. When Kyohei becomes badly injured, Sunako steps in and defeats the leader of the gang, putting everyone in shock.

The boys wonder if they're taking advantage of Sunako's cooking, and get a job at a fancy restaurant in order to lessen her burden. Kyohei wishes to eat nabe at a kotatsu, as he has never experienced the winter tradition. Kyohei goes shopping with Sunako, only to have the entire marketplace misunderstand their relationship. To add thing up Kyohei's fangirls appears and play around their grocery. Kyohei later lends a shopkeeper a helping hand, in return for some vegetables. Meanwhile, Sunako goes out to construct a kotatsu. In the end, they end up having an enormous kotatsu feast.

The boys take Sunako, along with Noi, on a trip to the hot springs. Sunako tries to do everything she can do so that Takenaga and Noi can be alone, which leads to the fact that Kyohei and Sunako have a very intense ping-pong match. As the match ends, it is shown that Kyohei and Sunako share a kiss by accident.

The hot springs manager has been attacked, and Sunako decides that she cannot pass up the opportunity to snoop around a real crime scene. However, the true culprit resents not only Sunako snooping around, but also her being accompanied by the four bishōnen. It turns out that the wife of the manager is responsible, plotting to kill Sunako by burning her alive in the storage room, by which Kyohei is able to rescue her out of. When they confront the wife of the manager, who insults Sunako's appearance, Kyohei states they have kissed

Sunako needs to be tutored in math, since failure to do so will cause the rent to increase. Kyohei dresses up as a nerd and studies hard to teach Sunako not to run away from her issues, however this causes an uproar among the female students.While doing so Sunako remembers the incident that she kissed a radiant being (Kyouhei) which causes her to react badly. Later Kyouhei makes her understand that a passion-less kiss is nothing. Unfortunately, Sunako still failed the exam due to putting the right answers in the wrong math problems

Mine comes and wreaks havoc, but luckily Sunako calms her down and teaches her how to be a good housewife. But when Sunako gets invited to her aunt's party, she has to try to brave the road to womanhood. In the end, Mine tells the boys to make Sunako a super lady.
