If you're a fan you've most likely seen the show 'Thankyou for Waking Me' which is what made me, and probably a lot of other girls, fall in love with the group. If you haven't seen it:

Kyu Jong!! <3 He's definitely my favorite in the group but it seems like he's one of the least popular. Is that true? I like how he has more meat on him than the other guys. And he seems the most shy and humble. But I don't like how he's always trying to hide his chubby cheeks.
