Koi da Ai da wa Sateoite

On the way home from work, Okazaki Taichi finds a man named Fuji, sleeping on a bench one day. Okazaki ends up bringing Fuji to his house, and somehow, he ends up on top of him, and they become friends with benefits. It's the start of an erotic BL between a heterosexual salaryman and a lewd bartender.☆
