I agree, I think that they both acted like adults and was upfront with what they want from each other. Our Yeomin asked if it was OK too keep having feelings for him, and he said it's up to Yeomin while being clear about boundaries.
Yeomin finds him as someone he can rely on which is rare since he is so used to being alone. I think he is mature and knows what he's getting into.
If there is one thing I would like to comment on against the ML it is the fact that he has no regard for Yeomin's physical state or his schedule and how having constant sex is affecting his body/health.
fr i think they forgot how to use their brains
unless theres a novel and the ml is a dick
why do yall hate him so much
like if he didnt tell mc what he wanted than yeah id agree he's a dick but he specifically told him what their relationship was currently and even gave mc the option to either stay as like "friends with benefits" or just friends/strangers
