Summary: Chiho Yoshino is a 15 year year old who still has a childish face and is ready to be an adult in order to be closer to the Somei-sensei, the one she loves. She plans to confess to him on her last day of middle school, but all goes wrong and instead she asks for his email address. To top it all off she's recently been having a dream/flashback from when she was in elementary student and some popular guy from school saw her underwear. Can this get any worse for Chiho?
