Cinderella no Kake
The Cinderella Solution·シンデレラの賭
Charlotte, a graphic designer who typically dresses in loose jeans and often has messy hair, is challenged by her best friend Gabe to attract a romantic proposal within a month. Gabe, who doesn't view her as conventionally feminine, offers a thousand dollars if she succeeds. Rather than accept the challenge passively, Charlotte chooses to respond by making a significant change to her appearance.
