On the latest episode of SBS' 'Running Man,' 2NE1's Park Bom left Lee Kwang Soo quite flustered with a warning.

During the episode, Park Bom, Minzy, Yoo Jae Suk, and Lee Kwang Soo traveled together in the car as one team. Park Bom shared that she would like to change the team's image because their current image for the fans is "scary unnies."

Yoo Jae Suk replied, "It's because you guys are charismatic on stage and wear thick eyeliners." Park Bom added, "That's why we made it light today."

After seeing their faces closely, Yoo Jae Suk said, "It really is. They're kind eyes today. Minzy really looks like a girl next door." 

Then, Lee Kwang Soo complimented Minzy by saying, "Minzy's eyes are the type of eyes that I like."

After hearing his comment, Park Bom exclaimed, "Stop flirting. Why are you flirting with my sister? I think you crossed the line," making the viewers laugh.
