ARI SHAPIRO, HOST:
In South Korea, concerts and sporting events came back this year with a caveat - to keep people from yelling coronaviruses into the air, no cheering was allowed.
ADRIAN FLORIDO, HOST:
That meant baseball without crowds making noise or K-pop without fan chants.
KAYLA BALBA: I think originally, it was created by the fans to show the members and the group support during songs. But now a lot of groups actually do, like, fan chant guides so that you know exactly, like, what to say and when.
FLORIDO: That's Kayla Balba. K-pop fans like her have dedicated scripts they chant together during specific songs. Here's the BTS Army, the supporters of the band BTS, chanting each member's name at a concert.

UNIDENTIFIED PEOPLE #1: (Chanting) Kim Nam-joon. Kim Seok-jin. Min Yoon-gi. Jung Ho-seok. Park Ji-min. Kim Tae-hyung. Jeon Jung-kook. BTS.
BALBA: And it's mostly so that, like, the fans can be involved in the performance but is also - it also contributes to the atmosphere of, like, the overall concerts.
SHAPIRO: Balba went to a few concerts earlier this year, and there was lots of clapping and noisemakers, but...
BALBA: It was like, absolutely no screaming, singing along or dancing or standing up.
SHAPIRO: Then this past weekend, she got tickets to see the boy band Stray Kids.
BALBA: So I just got to the venue, and so there's so much going on. Like, there's people taking pictures. There's people, like, running for freebies. It's, like, a whole free-for-all. And then there's people, like, trying to buy slogans and stuff. But other than that, there's just a lot of fans excited.
FLORIDO: Excited for merch and the music and one more thing.
