The poster finally came out, and I'm pretty sure this movie was just made for him!
He stands out the most of the four younger characters, and his name is listed first among those four. It looks funny and fun just from the poster, so I can't wait until we get to see an actual teaser.
It will come out in Korea on January 7th, so hopefully we can all find a way to see it soon after! If I find any previews or trailers, I'll post them, too ^-^
