I went to COEX to see Byeon Woo-seok before it got colder.
I usually go to Samseong-dong once a year, but I went 4 times in a week.
It doesn't seem like the video is released regularly, so if you're going to see the commercial, dress warmly.
The bus stop in front of Shilla Stay is a good place to see Byeon Woo-seok's commercial.
