Title:
トモちゃんは女の子! (Tomo-chan wa Onnanoko)
Author:
Yanagida Fumita
Tomo Aizawa was able to successfully confess to her crush Junichirou Kubota. There is only one problem: He just sees her as his buddy.
He thought that she was a boy until they went to middle school together, because her grade school was in a different school district.
