"The Wallflower" is about a girl named Sunako who was called ugly by 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 worse, Sunako's aunt, the owner of a huge mansion where four very handsome high school students live (for free), demands the boys to transform her niece into the "perfect lady," and in return they will be able to continue living there for free. They are given a deadline and if they are unable to uphold their deal then they would have to either pay a lump sum of cash or vacate the premises.
