Kouhei Ueno

A bespectacled friend and classmate of Tsubaki. He and Oka have been dating for about a year but try to keep it a secret from their classmates. Only Tsubaki and Urabe and later Hayakawa are aware of their relationship. He often fondly recounts to Tsubaki his experiences with Oka Tsubaki in turn gets romantic ideas to use on Urabe from Uenos stories. He also seems to possess a possessive style as he wont take Oka to the beach because other guys will see her in a bikini and jealous when other guys talk to her.
