My friend talked about this manga with me but she doesn't know the name. It's about a guy that were in love with a married old man (the guy called him Professor/Sensei), and the old man hired a man, that told the guy he was a detective, to shove off this guy and they had sex but turned out the guy and the 'detective' fell in love with each other.
