Jeon So Min sent a warning message to her ex-boyfriend. 

On the September 19th episode of SBS's 'Running Man', the cast and guests had to guess the results of a poll of teenagers to 60 somethings asking who seemed most likely to avenge someone else hurting his/her feelings. 

The cast immediately singled out Jeon So Min and she shared some of her petty acts of revenge including tangling wired earphones admitting she is the one who usually pays back. Then she added, "On second thought, my biggest revenge is working hard like this." 

She then directly looked at the camera and sent a warning message to her ex-boyfriend saying, "Are you watching this now? I'm going to make you see me whenever you turn on the TV."
