The Wallflower is about Sunako Nakahara, 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.”
While the four of them manage to make Sunako physically beautiful enough to become a lady, the problem lies with her attitude and interests. 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.
