It's a yaoi about this guy who meets this guy younger than him. The guy is said to be a real playboy but he is actually impotent. The younger guy likes him but he didn't know, so when the he made a move on the guy, they guy suddenly screamed that he was impotent.

It's something like that, can't quite remember.

Otona Keikenchi well maybe 😕 there was an impotent guy but dont know
