@kitkatt430 Apparently it's pretty common for Koreans to wear masks when they are going to be in a place with lots of people, or if they are sick. It confused the hell out of me for a long time too lol. But yeah, they also wear them while they're home too.
@raptorfactor because it's a concert? no one could have imagined the venue would build such a flimsy structure that would tip over.
