Seishun Cinderella

High school girl Shion decides to confess to the boy she likes. However, before she can even say "I like you," she receives her answer: "If you want to confess, at least do something about your appearance."

Ten years later, Shion works and has much more style, but still can't manage to have a normal relationship with a man. Ever since she got that answer, time has stopped for her. By pure chance she finds a photo from that time and, as she tears it up, she finds herself catapulted back to the same time as the photo. The modest high school girl from ten years ago has returned, but now she knows how to put on makeup and dress fashionably. And so, Shion has a second chance to live her high school life and erase her regrets.
