Yeah, you heard it right..
he just seems like that kind of guy.
Now...let's analyze some evidence
Jonghyun is beautifully destructive ...like dinosaurs ruining cities- but in a way, it's almost beautiful ;-; ...if that even makes any sense
Sometimes he just looks like he has total power over everything -almost evil looking *-*
but we all know Jonghyun is not completely evil ...
...but just look at his dino features !! (this is just living proof that dinosaurs still roam earth today)
The last piece of evidence is that he likes to bite his fellow bandmates. If this doesn't prove that he is indeed a dinosaur, I don't know what will
