God, it's been so long I can't remember who the First Girlfriend is. I remember Hanada is the voice actress and Tsukiko is best girl, and I remember psycho teacher, and aunt's friend with the short hair, and the most recent one at the driving school, but I'm completely blanking out on everyone else. EDIT: Oh I remember the girlfriend he actually really liked that moved away, the fitness girl, too.
Also, those were some Yandere eyes there when he said she was his first girlfriend.
