Black Cinderella

Kamiya Manaha is a girl with little self-confidence. Her childhood dream was to enter the Miss Seiran Contest, a beauty pageant for high-school students. Despite seeing herself as an ordinary girl, she enters the pageant. She then meets Tachibana Keigo, a handsome, self-absorbed boy and Shimamura Sora, a mysterious transfer student. At contest time, Manaha cannot keep her excitement in, as she is just steps away from the very stage she’s dreamed about for so long. (Source: Lee C at MyDramaList)
