Номія Такумі

He, along with Yamazaki and Miwako, is first introduced on episode 14 of season 1. He is the type of guy who could "throw a cellphone in the sea full of women's numbers, without caring at all" as said by Mayama. Nomiya is Mayama's former boss at Fujiwara Design. He also likes Yamada, and tries to visit her whenever he can, although he is aware of Yamada's feelings for Mayama. Mayama tries to act as the middleman as much as he can in order to protect Yamada, as he considers Nomiya a playboy. However, later in the series, Nomiya comes to realize that he himself has truly fallen in love with Yamada.
