Shouta is introduced as Kaede's ex-boyfriend. Despite the break up, Shouta still visits Kaede, often bringing gifts from his mother, who wasn't aware that they weren't together anymore. He still seems to have feelings for Kaede. He befriended Dino, so he often hangs out with him sometime at Kaede's apartment (whether she's at home or not) or elsewhere. Shouta seems to be on good terms with Kaede's friend, Yamada, as well.
