I Think People Are Giving Bum A Bit Too Much Credit

Yeah, he’s hella messed up and not as innocent as a lot of fans think he is but let’s face it, Bum is not the sharpest crayon in the box. I don’t think he’s some master manipulator, maybe he’s trying to be but I certainly don’t think he’s very good at it.
He’s also notably obsessive. The fact that he keeps a list doesn’t really surprise me but I doubt he’d be willing to try any of those things on his list if Sangwoo wasn’t in such a good mood.
I also don’t think that the Bum we’ve seen so far is fake. He’s just gotten too cocky and secure since Sangwoo is being nice to him and he overstepped his bounds.
