BTS have been landing US number ones, sitting on Ellen’s sofa and breaking all kinds of records around the world, but the football BTS ‘Bento’s Boys’ - named after the team’s new Portuguese coach Paulo Bento - have been selling tickets almost as quickly as the seven-strong group.
It's not just the fast-paced and fast-passing style of Bento and the gold medal at the Asian Games in September that are bringing the fans back.
It is also, so the theory goes, down to the good looks of young stars such as Tottenham Hotspur's Son Heung-min and Italian-based Lee Seung-woo.
"People say I'm cute, but I don't know if I'm cute enough," Lee said last month.
"This big support from fans makes us play a better game and be more responsible. We really want to give back fans' support by playing a good game."
That has been the case so far. Ahead of October’s impressive win over Uruguay, Seoul World Cup Stadium sold-out with over 64,000 tickets.
Four days later, the game with Panama was also a full house of 26,000 in the relatively small provincial city of Cheonan on a chilly Tuesday evening.
What was really impressive was all tickets for both games were snapped up within hours of going on sale. Also notable was that there are more female than male fans turning up.
"The ratio of male to female in ticket sales was 7:3 in previous matches, but for September friendlies, it was 4.5:5.5, meaning there were more women than men," said Yi Cheong-seop, head of the KFA's marketing team.
"We're also seeing more teenage fans than before. We think that these fans are having more interest in young star players than the team.”
If they come for the stars, they may stay for the football.
There have only been four games under former Portugal boss Bento, who took Cristiano Ronaldo's side to the semi-finals of EURO 2012, but results and especially performances have been encouraging.
Korea's two wins over Uruguay and Costa Rica went down well, as did a draw against Chile.
The feel-good factor is back. The after-effects of the 2002 hysteria and that run to the last four of the FIFA World Cup helped fill stadiums for a while but over time the nation slowly fell out of love with the team.
The regular changing of coaches, the unremarkable football and the lack of personalities resulted in dwindling crowds and falling interest.
The nadir came in the tenure of Uli Stielike. The German started well by taking the team to the 2015 AFC Asian Cup final where they lost - unluckily so, is the feeling in Seoul - to the Socceroos.
That was as good as it got, with qualification for the 2018 World Cup a painful process - the coach managing to lose the players (not an easy thing to do in Korea), lose to China for the first time in a competitive game and then lose his job with two qualifiers remaining.
Under replacement Shin Tae-yong, the World Cup was not a success, even with the magnificent win over Germany.
There were positives to come out of the tournament, with gloveman Cho Hyun-woo one of the stars.
Known as ‘De Hair’, for his love of Manchester United's David De Gea and distinctive hairstyles, Cho outperformed the Spaniard in Russia.
Others are hoping to catch the eye against the Socceroos and Uzbekistan next week.
Na Sung-ho and teenager Kim Jung-min were active in the Asian Games in August and will make their senior debuts over the next few days, as will defenders Lee You-hyeon and Park Ji-soo.
It’s not all about the rookies though. Ex-Bolton and Crystal Palace winger Lee Chung-yong will get a first and possibly last chance to impress Bento ahead of the 2019 Asian Cup.
They should all get some playing time as there are plenty of absences besides Spurs star Son.
Captain Ki Sung-yeung is staying with Newcastle United and star attacking midfielder Lee Jae-sung has been left in Germany. Other mainstays such as Jung Woo-young and Hwang Hee-chan are also out.
Experienced defender Jang Hyun-soo is gone for good, after being found guilty last month of falsifying his community service records - even those players who win military exemption thanks to medals at Olympics and Asian Games have basic duties to perform.
Military exemption is not on offer in the Asian Cup, which is partly why it has not always been a priority for a country that last lifted the trophy in 1960.
For a generation of players who don’t have to worry about the army though, it is the one major international trophy they have a chance of winning. And fans in Australia will at least get a chance to see this version of BTS.
