damn those eyebrows though..

I saw an episode of him in Running Man (btw he was funny as hell) and when asked how old he was bc of his voice they translated him saying he just turned 18!!! Did they translate wrong?

He is very good in Potato Star. I know he is the lead there n u dont see the age difference at all wt his costar but he will be a great leading man with more grown up themes in the near future, so watch out world!!!!

Still drooling..*pervert noona* ?

Those lips. I hate myself.

Lookimg is legal. Looking is legal. Looking is legal. He has the most beautiful nose. See , i looked properly.

his deep voice is what's making me crazier!!!!

Laughed so hard when I read the title. HAHAHAHAHA. Jailbait? yes, he is. :( I always feel guilty whenever I look at him. I've always thought he was a cute little kid but when I saw him in I Miss You, holy moly! Noona feels all over me! Ahhh too much feels, too much

so hot!! but sooooo young

He's entirely too handsome. Watching him grow up has been surreal since we are of similar age, but wow, I wish I looked this good at 16. He's not even in his prime yet! I'm excited for his future though, he's such a talented boy.

He's a natural.

I find him cute as a teenager. I think Yoo Seung-ho the "little So-Ji Sub" is and will be the futuer noona killer

I'm only have a year older than him oh my goodness, my feels.

I meant half lol

But but... He's 18 Korean age!

One thing fantastic about the new year is YJG announcing that he's 18 on Runningman.

*right-click save* every damn picture.

If you're already at your prime as a teen, I can't wait for you to reach adulthood.

He is absolutely beautiful...

But WHAT'S UP with those yoga pants in the chair photo?! Totally wrong look.

Thank God I am not attracted to guys younger than me..even a YEAR younger is a big NO. NO...LOL. I admire him as an actor and he does remind me a little of Kim So Hyun :)

He was born in 1997...Wow, I'm feeling old. Do I count as a noona? 'Cuz I'm pretty sure, if he saw me on the street, he'd call me ajumma. T__T

So young yet gots a wrinklely forehead already. I'll visit y'all

I haven't read all the comments, but as the mother of a boy just a year older than this one, I am going to be a Debbie Downer and ask- if this was a 16 year old girl, and these comments came from a bunch of men leering, er, sorry, 'just looking' at her, would that be okay?

Double standard much?

Him and Zelo (BAP) will forever be the death of me. His freaking voice tho for a 16 years old.. I really can't deal with this /close tab/

He is such a talented person. Like Yoo Seung Ho, he is extremely gifted at emoting beyond what would be expected of his (so few!…Sooo Few!! *le sigh!*) years. How does he do it? How does he do it, indeed. I am hooked. I wish him many years and successes. I hope that he continues to develop as an actor, and that he doesn't "get wild" or etc… the way that some very young actors/actresses can go. Hopefully, he has a strong emotional and professional support system/friends/family that will surround and help be there as he becomes (even more fully!) a matured person.

Best wishes!

he look like the main male lead in Fabulous Boys(taiwanese drama) i forgot his name... hes hot.
