Doubt!! (Izumi Kaneyoshi)

Ai has been a jimmies (slang: girl who is plain and behind in fashion) all her life, and she's never had a boy as a friend, and much less a boyfriend. She's always lived in the shadows, and blamed others for her misfortune. One day she becomes the laughing stock in front of her whole class, including the boy that she likes, because of her Cutey Bunny panties. That is the turning point for Ai, and she decides to become a fine woman and start over in a high school where no one knows her. Thus begins Ai's search for love. Includes a oneshot entitled The Day of Finals.
