On May 26, K-pop boy band BTS (Bangtan Boys) brought their "2017 BTS LIVE Trilogy Episode III: The Wings Tour" to Sydney.

Playing to tens of thousands of eardrum-shattering screaming fans at the Qudos Bank Arena, the 7-member group put on a killer show.

BTS made history last week by being the first K-Pop group to be nominated and win at the Billboard Music Awards. They beat out household names Justin Bieber, Selena Gomez, Ariana Grande and Shawn Mendes to snag the trophy for Top Social Artist.

That Top Social Artist awards though. 👌 Congrats, BTS! 🏆 #BBMAs A post shared by Billboard Music Awards (@bbmas) on May 22, 2017 at 9:49am PDT

Their fandom, called A.R.M.Ys, are a force to be reckoned with. It's clear the Korean pop sensation's international popularity is no joke. Tickets to their Sydney concert sold out within hours of going on sale.Given this was their first event following their ground-breaking Billboard win, Aussie fans were made to feel extra special.Leader Rap Monster said, "Tonight is very special for us because this is, for Sydney, our first show after our Billboard Music Award. Guys, thank you!"He continued, "I must say you guys live in such a beautiful country. If I can't live in Korea, I want to live in Australia.".Member Jin, who recently trended on Twitter as the "third guy from the left", referenced the Aussie fan project of glowing red hearts by showing off his own hand-made red heart wristbands.He commented, "I'm happy to be here tonight with all of you. I feel like I am born again. So many heart in here and I have heart too. (reveals hidden heart wristbands)."The boys were on fire during the concert; their singing, dance choreographies and fan interactions were all on point. They were "legit", a local catchphrase they caught onto and loved to use.So what's next for the band? Maybe an MTV award and/or performance? For now, tell us which member is your bias!- Leslie Yu
