f(x)’s Krystal was caught staring down at KARA's Han Seungyeon.

On May 17, a photo was posted online with the title "Krystal who looks like she is going to hit Han Seungyeon.”

In the revealed photo are snap shots of 13th broadcast of SBS 'Running Man.’

In the photos Gary and Han Seungyeon are solving problems as a couple in the front and Krystal is staring down at Han Seungyeon from the back with her arms crossed.

Viewers who watched the broadcast are saying that Krystal has a rude attitude. The capture makes it seem like Krystal is seen to be glaring at her and her expression was more emphasized due to her posture of having her arms crossed as was as tilting her head to the side.

People are commenting "Wow she is a total senior to her and for her to look at her like that", "Her face expression is scary", "isn't it because this was edited?", and "I think it's the angle".

As always viewers are divided on the issue as those criticizing Krystal while others don’t take the issue so seriously.
