If MC was feeling some sort of doubt he had every right to confirm with ML, doubt can always find a way to seep through so asking just to confirm and double check some things is perfectly fine. Reassuring someone of something is always better than letting the doubt burn and fester up.
MC also has every right to say he realized he was uncomfortable with the fact that ML is sleeping with others. But in response ML also has every right to break up with MC if ML still wants to do his job.
MC knew what he was getting into with ML but that doesn’t make him at fault for feeling doubt or uncomfortable with some things. If ML want to break up with him because of that, let him.
They both have 2 different feelings on things that heavily impact a relationship. It’s best to sort things through if they want to stay together but clearly ML doesn’t want to communicate peacefully judging by the fact that he won’t tell him anything and he broke a whole ass cabinet or whatever that was.
If one is uncomfortable with the thought of the other sleeping with someone else even for a job, while the other refuses to quit the job nor elaborate why. I see no way the relationship can continue, and judging by the spoilers it only gets worse

HELL YEAH. The moment my partner doesn’t give me a reason is the moment I end things and stick to being friends cause friends >>> lovers.
Judging by raws, it indeed gets worse haha. Brace yourself. Both are at fault here for sure though, MC broke boundaries they agreed on earlier, ML isn’t communicating as much and being aggressive, both aren’t really trying to understand each other or at least MC can’t because he doesn’t know why ML is doing sex work. He just accepted it because MC wanted to date ML and thought he could handle it.

YESS
Yeah totally agree with that, it takes a minimum of two to have a relationship so both are clearly at fault.
MC thought he could handle it but if he realized he actually couldn’t, it’s perfectly fine to bring it up and if that’s a deal breaker for ML then so be it. Especially when they both aren’t complying with stuff, like one is feeling doubtful while the other won’t explain anything, it’s obviously gonna cause a big division between the both of them.
They are both at fault and it was upsetting me how so many people only blamed MC.
Nahh and I know author is just gonna immediately go over this like it was nothing.
