This episode was so touching, I replayed it serveral times!
where it revealed behind the scenes.
Kim Jong Kook, I really didn't expect that was you.
All along I thought was others.
I just love your smile, your shy smile
Thanks for making my day.

Thank you running man for this show, 

a show that has been running for years.

a show where everyone would watch every week or so,

a show where we discover our new idols, 

a show where made us laughed and cried

thanks to all the crews, productions. 

fighting! 

I will never know this song if not for running man,

it just fits perfectly into the scene, the ending song. 

Kim Jong Kook, you're so sweet!
if I were the girl, my heart would be melted too.
with a bouquet of flowers and a love note.
Although it was just a part of acting,
still it touched my heart and I nearly cried :')

Thank you from the bottom of my heart.
