Girl's Day's Hyeri will guest on KBS's quiz show '1 vs 100'.

According to an official broadcaster from KBS, Hyeri along with gag woman Oh Na Mi, fitness trainer Sean Lee will participate in the recording of the show on October 5th.

A rep from the production team said,"Usually the average score of the celebrity participants is between 60 - 70 out of 100, but Hyeri scored 10 points higher than the average. We thought Hyeri was just an idol who lived off her cute image, but now we see that she also studied well. She really surprised the production team with her score".

This episode will be broadcasted in mid-October.
