There is news that Cha Eun-woo appeared on Yoo Byung-jae's YouTube channel. The title is Cha Eun-woo's birthday party that can't be helped with a smile.

The concept was to have the participants dress up and prepare a birthday party for Cha Eun-woo's birthday, and see Cha Eun-woo smile. Everyone prepared hard and came out with funny makeup on, which made us laugh a lot. It was so funny to see Cha Eun-woo try not to laugh.
