DAY6's Young K, who appeared in 'Dream High' before his debut.

It is interesting to realize once again that Young K appeared as a dancer in seasons 1 and 2 of 'Dream High' before his debut. Since it is said that even Jang Wooyoung didn't know about this past, I imagine it must have been even more fun to hear the story from the two of them. I am also curious to see what he looked like back then, looking quite different from the Young K of today.
