Probs so mc wouldnt feel taken advantage of or I get their arrangement isn't normal doesnt mean they'd be ok with doing "gay"things or thats an absolute confirmation of ones feelings. He could have easily left feeling like he was being used or get grossed out or can do that but isnt actually "gay". We know what our mc is and how he feels but u cant assume that just being upfront is going to be fine like theres a reason for that thinking and the way he went about ut
The thing is they didn't know if their feelings are mutual. Their relationship started off as *business only*, so a one counter such as like that wouldn't mean they automatically confessed that they like one another. It could mean it was just an extra service because again, their relationship in that ch was only business.

Until ml gave mc the money after what happened in ch3, I'm sorry but that was such an ah move especially bc he ends up confessing later on
I mean, it's true that was their deal, but why would he make feel mc like he sold his body when they actually like each others? Meh :/
