[All] Eunwoo's younger sibling who appeared briefly on You Quiz

I heard that Cha Eun-woo's younger brother appeared on You Quiz.

I was surprised to see the photo too
On June 11th, the story of a person who became an intern at a semiconductor company's vice president was introduced.

At this time, a scene of company employees walking side by side was briefly shown, and it is said that Cha Eun-woo's younger sibling was present at the time.
I watched this broadcast, why didn't I know about it?
This is really awesome

I'll have to watch it again
