I feel like markim are more comfortable more then mint and mark. I think mark n mint they kinda look little bit shy to each other when they act together idk too but in my opinion just feel like that. Anyways wait for both
I think you know why M&M are shy hahah But they're not shy though, you know, both of them had news and been to be forbidden, however it got better now though. I think he have chemistry with both of them, and feels comfortable with both of them too, but it's the sense of what kind of chemistry they have.
Markim - Mark treat her as if she's a boy. Instead of a sister or a sibling, he sees her as a friend. Their chemistry is not a sweet, intimate, warmth, genuine, or an adorablity kind of chemistry, their chemistry is more to the bickering and love-hate kind. The reason why Mark can do anything freely with Kim because there's no hiding between their relationship, and there are no suspicious feelings towards them. That's why he's being all open to her.
MTeam - If you go on NM2 thread, you will understand why they're like that. I actually think he's more comfortable with Mint than Kim, however you can tell, they're being cautious because...yeah..don't want to say it here hahah He's more intimate with this girl than with Kim. Okay, I don't want to say much about these two on this thread, you have to go look on NM2 thread, and you'll know why.
