VIDEO: Lee Kwang-soo x Jeon So Min's Finger Flicking Battle!

Have you seen last night's episode of 'Running Man'? 

On October 29 aired an episode of SBS 'Running Man', Korean stars Lee Kwang-soo and Jeon So Min showed their sibling-like chemistry during their game time. 

They each took the turn and did a finger flicking battle at each other's forehead. First, it was Lee Kwang-soo's turn, to do a finger flick at Jeon So Min's forehead. Merciless Kwang-soo flicked his finger on So Min's head and So Min yelled at him for it.

Then Jeon So Min tells Lee Kwang-soo that now it is her turn. Then Lee Kwang-soo sits down on the chair and waits for Jeon So Min. 

But instead of flicking her finger at Lee Kwang-soo's forehead, So Min purposely punches his forehead for being merciless to her.
