[talk] Photos of NCT Mark taking over McDonald's posted on the official account

McDonald's Korea official account

I found out about Mark's McDonald's model through a video spoiler from the official McDonald's account😆
In the video, the store window is covered with cute Mark posters.
They say there's a secret hidden in the poster attached to the store! I wonder what the secret is, haha.
Now all that's left is to take a polite photo in front of this poster😏
