I wouldn't be surprised if everybody in the world knows it's a game, but are professionals, so they're all acting along when around the MC. It wouldn't shock me if that guy went off and had a smoke break or a drink like "oh good, I'm done playing Random Attempted Rapist A for today - also, why is the player a dude?".
Nearly spit my drink out at "who's event is this?"
it'd be nice for the MC if one of the eventual 11 targets was a yuri route so he could have a safe exit at the end. I suspect 100% not just from the premise tho, unless they do a reverse trap.
