The comments I read were assuming he was cheating in the present and that is why he is so cold to the MC. It should be obvious that at the time of this flashback they were only friends, not boyfriends so no cheating was involved if it were consensual. Ofc being rapes is not cheating though if that is what this was

Y’all stop assuming blondie was cheating on him for all we know he was tied up and even after they admitted that it was rape you guys can’t just assume because you don’t like him let’s just wait to actually find out and also hood on brown hair he didn’t do the whole OMG YOURE CHEATTIGJ ON MÉ thing he took that guitar and fucking bashed their skulls in
