Im about to start this, did the omega cheat on his husband?

nope theres ni cheating

I saw ppl saying the uke got raped is that true?

I don't wanna spoil but there's sum past trauma and misunderstanding in the mc's backstory

ML'S cousin try to rape MC and MC thinks it's ML and hate him, later after his memory lose and get close to ML he realised ML is not the culprit but it's his Cousin brother....

nope, he wasn't rape

Ohhh thank you sm! I actually dont mind spoilers unlike most ppl
I actually so like them so i know what to expect when starting a story
