One day, she meets someone else who does not present his true self at school: a quiet, glasses-wearing boy called Miyamura. She'd assumed he was bookish, and possibly an otaku, but Hori couldn't have been more wrong. Outside of school, Miyamura is a friendly guy with many piercings, and he's not very good at academics.
