omg he didn't treat him so bad? girl be for fucking real now lol. that's such a low bar you have there. he literally slapped him in the face leading him to bleed, almost gangraped him, and caused him to bleed in his first time. and what about MC having his own fault? ML wasn't genuine about him from the start, so whether MC truthfully prayed for him or not didn't matter. he was a thug and was planning to screw him over from the beginning even before he knew about the fake prayers.
the author did a good job portraying MC's stockholm syndrome and ML's gaslighting so you end up believing that it's partially MC's fault, and had to shower us with a long fluffy arc so we forget about the shit the happened at the beginning of the story.

I've read many omgaverse manhwas but this is undoubtedly one of my favorites that deserves 5 stars. The story is not as dark as I was lead to believe. Honestly the ML didn't treat the MC so bad, it's not rape but mostly dubcon. MC too has his own fault alright. And most importantly to me, the Omega is not feminized by being called mother. I really love this. Give it a try.
