I think hyung is the brother of heebum from the first family

Yeah, now I want to know how he met heebum with cross dressing and how that bitch eunbyul fall for YW after they did to YW

It's very obvious that Min Woo set him up. Min Woo being jealous of the attention and kindness the VP was showing YooWon. So, he lied about the plane and he probably took the shells to set up Yoo. THat way, he can make the girl turn against Yoo and he can have her. Punching him was probably part of looking all heroic. The dude is evil.
And I also wondered if Hyung might be HeeB's brother, but we never hear him talk about family and all we know is a father and a mother-who-is-not-his-mother, so maybe stepbrother or just someone who looks HeeB-ish.

Yeah I think so too because from the previous chapters heebum said he is child from another woman
I like hyung so much. Its also interesting to see how hyung might've influenced yoo won to go to Tae Poong High (I mean, they're so poor and Tae Poong is an exclusive private school, he might've gone there on a scholarship). And to think it was hyung who inspired him to study!! lol and hyung's personality is like hee bum's. they look so tough and seem to not care on the outside but they're actually soft inside. It's cute!
Idk but i have a feeling it was that min woo kid who framed yoo won up. i mean, why lie that he stole one of his airplanes right? idk. i just dislike tose kids so much. even the teacher, why not reprimand the one who got physical? can't you see how bad the kid was beaten up? no matter what the reason, teachers shouldn't tolerate violence right?
