Help? (Any Kpop lover out there? Or anyone that wants to help?)

So I need help with deciding which one of these guys has more of a mysterious look.

First::
JunHyung (B2ST)


Second::
JR (NU'EST)


and lastly
L/MyungSoo

I know , I know L is smiling (xDDD) but I couldn't find one where he was serious (T_T)

(I don't know if it'll work but I hope it does haha ^^")

so which is more mysterious?
