Congratulatory advertisement displayed on a large LED screen in Myeongdong to celebrate Seventeen's Jeonghan's birthday

I hear news that fans have prepared a celebratory advertisement using a massive LED screen in Myeongdong, Seoul, to commemorate Jeonghan's birthday. Thinking about a video announcing Jeonghan's birthday being shown right in the middle of Myeongdong, where so many people pass by, makes the fans' dedication feel truly special. I am curious to see how the actual advertisement will turn out, as it seems like it will create another memorable moment for the fans who visit the site in person to celebrate the birthday together.
