Hino has a playboy aura and reputation which makes it difficult for him to have male friends. Furthermore, he's been in love with the quiet and aloof male classmate of his since high school. Hino took the same college as Yaku and basically stalked his interest. He tried approaching him, being friendly and kind. However, Yaku doesn't budge, rather he found Hino annoying. And when Hino finally gets his attention, they end up being sex friends. Still, having the chance to be that close with the person he loves made the pain worth enduring.
