So you just read how Lee Kwang Soo is hotter than you think� Welcome to the second of our ILY 'Running Man' series, where you'll be reminded on why fellow 'Running Man' member, Kim Jong Kook, is like a hard-boiled egg: hard on the outside yet soft (and cute) on the inside.

Kim Jong Kook is refereed to as the "Commander" and "Spartan" in 'Running Man'. As you can see, they usually draw fire around him.

Because everyone usually fears his competitive and tough nature.

But there's more to mister Kim Jong Kook than we think. Despite his nicknames and his built (all that muscle), he has a very soft interior. For those who watch the show religiously, you probably already know that Kim Jong Kook can be very very cute.

He gets rather shy around female guests.

On SBS's talk show 'Healing Camp', Gary shared how Kim Jong Kook is in fact shy in front of girls and is the type of man to want a confession first. He said, "I tried to hook him up at a private gathering, but he was just sitting like a rock."

Who can NOT like South Korea's forever little sister, Moon Geun Young? Watch Kim Jong Kook melt from just a single word from her.

Kim Jong Kook's mom once shared in an interview that her son is a total daughter when home and she often gets bored without him. She said he brings her around places whenever he can. Now that is very adorable.

Very capable of a wink.

Cutie patootie

I swear he knows himself that he can be quite cute #eyesmile

It comes out time to time, and that's why he's also the owner of the nickname, "Kookie".

Go to 0:44 hehe

#bromance, but cuter

Too good.

and OF COURSE, he was the cutest when singing and dancing to hit song, 'Lovable'.

Kim Jong Kook is a "Commander" and "Tiger" for great reasons, but underneath all that (muscle) he's a total cute "Kookie" with a soft heart and that's why we love him!
