I agree with the first part but the 2nd part is a hell no. Chunwoo isn't playing anyone, currently in the raws he likes both & is very conflicted about his feelings, chunwoo is a complex character just like the other two nothing is simple.
He gets annoyed due to what happen in the past he doesnt want it happen again (I only know a few spoilers for this)

I can’t be the only one who feel bad for the red head, like he hasn’t done anything evil or even wrong. And knowing that the uke will end up with mc I feel like the uke is lowkey a bitch when the red head wanted to go out but uke is only after his body
