Tadashi Sakamoto
About
Tadashi is known as a player who never stays with a girl for long, since they all accuse him of being shallow. After spotting his gay neighbor, Haru, arguing with his ex-boyfriend, Tadashi becomes interested in him, though nothing serious ends up happening between them.
Tadashi attends the same university as Kazuhiko and the two live together for two years, though Kazuhiko eventually gets tired of Tadashi's womanizing ways and moves out. Years later, Tadashi and Kazuhiko meet again when their companies collaborate, and Tadashi proposes they start fresh.
