On December 13, NCT's Mark made a surprise appearance at a look-alike contest held in his honor at Washington Square Park in New York City.

Earlier, just a day before the contest, Mark had discovered a poster for this event and even shared the poster on his Instagram story.  The contest, scheduled for 1:27 PM, had already drawn interest online, but no one anticipated that Mark himself would show up in person.

As soon as he arrived, fans flocked to the idol, leaving no room as more fans mobbed toward Mark. Only after a few minutes of arriving, Mark was surrounded by hundreds of fans wanting to get a glimpse of the idol. Due to the immense amount of people surrounding him, Mark left the event shortly after arriving. Following the event, fans took to social media to share videos and photos of Mark being crowded by fans at Washington Square Park.
