The Wallflower (ヤマトナデシコ七変化 Yamato Nadeshiko Shichi Henge?), a.k.a Perfect Girl Evolution, is a manga series written by Tomoko Hayakawa. The individual chapters have been serialized in Bessatsu Friend since its premiere in 2000, and in 24 tankōbon volumes in Japan by Kodansha. The series was licensed for an English language release in North America by Del Rey Manga and in Singapore by Chuang Yi — under the name My Fair Lady.
Nippon Animation adapted part of the manga series into a twenty-five episode anime series which aired on TV Tokyo and TV Aichi.
The Wallflower is about a girl who was called "ugly" by a boy, the first and only person to whom she confessed her love. This incident sparks a life change, and as a result Sunako shuns all forms of beauty, both in herself as well as in life. Concerned by her change for the worst, Sunako's aunt, the owner of a beautiful mansion where four very handsome students live, offers the guys free rent in her mansion if they can turn Sunako into a "perfect lady" (referred to in Japan as the titular Yamato Nadeshiko).
While the four of them manage to make Sunako physically beautiful enough to become a lady, the problem lies with her attitude and interests (which Sunako has no intention of changing). Up until the most recent release in the story, they've managed to convince Sunako's aunt that her niece is indeed a lady befitting the mansion in which they live (and prevent the rent from skyrocketing to triple the required amount). However, in reality, Sunako has not changed considerably
