Didn't Junghyuk and the sunbae have a conversation to where they were talking about how he didn't really like the black haired dude and how he was only hanging out with him for the fun of it. If you think about it it means that Junghyuk was protecting him. (◡ ω ◡) Well I guess we'll have to wait and see...
I don't know what to say at this point...ಠ_ʖಠ
