Honestly

I don't think Naui or Muhyeok is at fault for either of this, yes, Naui is allowed to feel upset however, I think he would've preferred if Muhyeok had just spoken to him about it upfront. it's not about being a whore or blurting out one's insecurities, it's simply about the fact that Muhyeok didn't speak to him about it. Oh, and I don't think it's an overreaction for Naui to walk off angrily, the mixture of anger and alcohol isn't a good one after all
