I feel this in a personal level so I'm a bit biased..
I was crushing over this 1 guy and he accepted to go out with me after what 3 months of me courting him? Just to find out that he already has someone and want to make it an open relationship afterward, I mean should've told me before and not after we go out ╥﹏╥
So as much as Sunbae's is too desperate&pushy. ML is kind of leading him on too by giving hope (╬ ̄皿 ̄)凸
Let's be honest here, we only tolerate yeonwoo action in Ch1-10 because we know he's attractive.
If he's some ugly-bastard, I'm sure everyone would be freaked out by how he behave and threatened Bum.
Hwi-Bum is super cute and attactive though.
