Infinite Love for Running Man

Least favourite? It's hard to choose... Idk... 

Depends because sometimes Gwang Soo's betraying personality really irks me. Sometimes

. 

At first, it was Joong Ki! I mean, who can resist this guy right? 

But after he left (sob), it became Yoomes Bond!

Especially because I loved his Yoomes Bond episode so much! His true self is really sincere, nice, modest and he always thinks about his dongsaengs. Not just in RM but in a lot of other shows he does, he always gives others time to shine. 

He's also amazingly funny, witty and smart! He can surprise us a lot like how he always says he can't do things, and he does them anyway. He makes the audience laugh too much. He gets along well with basically the whole RM cast and he always always makes the guests feel welcome. 

He's also one of the strongest RM members (although he doesn't show it often) alongside Ace Ji Hyo and Sparta Kook. 

Honestly, without Jae Suk, RM probably wouldn't be as funny and I doubt any other RM cast member will be able replace his character :D
