You mean Seunghee and Inbeom? The guy who wear pink shirts?
That was Inbeom. Suhyeok is Inbeom's cousin, the helmet guy who attack Seungtak in alley.
Suhyeok is the guy pink and Inbeom is the bully.
Me! I can't wait until Seunghee actually befriends Suhyeok! I saw the raws and while I'm screaming and squealing I don't really know Korean and it'll be nice to have some context

I'm afraid you're mistaken them, the bully called Suhyeok, and the guy with pink shirt is Inbeom.
I'm following bbobariee (author) on twitter too and recently she/he posting Suhyeok sketch. Just try to google translate it.

I hope you're not confused again.
I hate pointless arguing, dear. Let me get the facts straight for you, okay?
In chapter 57, Inbeom was the one KISSING Seungtaek. In chapter 59, Seunghee thought he was stopping Suhyeok going out of school. In the next chapter he was confused that WASN'T Suhyeok.
The differences between Inbeom and Suhyeok are the hair and the eyes. Inbeom have more messy hair and squinty eyes.
The first link is clearly an error and I don't speak Korean but I'm 100% sure that those drawing are in fact Kwon Inbeom's chara design on the right and Suhyeok's on the left.
Now you can continue to be confused or whatever suits your taste.
Well! Here we go (again). I will just wait for Seunghee and Suhyeok development instead of trying to argue. It will be a waste of time. Good chapter though.
