To the author of the "I hate when groups perform in the rain" thread, here's proof that some artists like aespa do perform Waterbomb Festivals/Concerts.
I really hope they do not get seriously injured. But, I know that won't happen.
Someone will always get injured to some degree from slips and falls in these events.
I'm happy they're doing it, but, at the same time, as a concerned fan, I worry for their safety.
