Young K appeared on Jang Wooyoung's YouTube channel.
In the past, during my JYP trainee days, on Dream High 2

They say that both of them have appeared as dancers.

I knew Wooyoung, but I didn't know Young K was there.

I heard Young K said that dancing was a big fear of him back then.

I heard that during the early days of his debut, he raised Wooyoung by buying him drinks and meals.
