Hi! I'm searching for a manga. It's about a relationship were the uke thinks the seme only use him and don't love him, and have other relationships. They have sex in a restaurant bathroom were they were attending to those highschool reunions or something. I tought it was from Madarame Hiro but i cant find it.
PS. sorry for my shitty inglish (⌒▽⌒)

Hello, I'm trying to remember a yaoi manga I read a long time ago. It starts with a businessman using like an escort service online to find someone to have sex with. The guy that shows up is younger (maybe college age) but says sex is against the company's policy. They end up playing video games or something. The businessman calls him over again another time and they end up doing it. The younger guy wants to go out but the businessman says no. Eventually they do get together though.
