nope I don't think he knows, he didn't even know that Rei already had sex with a guy, Izumi can be dense heh
But that part was at the beginning of the manga so I may be wrong
No he doesn't no in the back stage light novel reí decides that isla u mi shouldn't know about him and shougo
I wanna see a scene where Izumi catches Rei and Shougo having sex how funny would that be, well doesn't have to be during maybe like right after they're done. Wait Izumi knows they're lovers right?!?
