Like the rest of the Internet, Tomorrow X Together love watching funny animal videos on YouTube. The five-member Korean group, pronounced “Tomorrow by Together” and more commonly known as TXT, is hanging out in the living room of a hotel suite on New York’s Upper East Side, talking about their favorite videos on the world’s second-most popular website.

They’re tall — the shortest member is 5’10”— dressed in stylish black-and-white streetwear ensembles, and sporting bouncy, shiny bobs worthy of a shampoo commercial. There’s plenty of room on the couch to spread out, but members Yeonjun (19), Soobin (18), and Beomgyu (18) have chosen to sit shoulder-to-shoulder, a testament to the close bond they’ve forged over three years of training together. Taehyun (17) and Huening Kai (16) flank them in chairs on either side of the sofa, leaning in and eager to participate in the conversation, which we’re having in English.

So, what else do they watch on YouTube? Soobin, the group’s bright-eyed leader, senses an opportunity. “I enjoy watching Tomorrow X Together videos!” he cracks with a cheeky grin.

The guys are in great spirits considering that they recently disembarked from a 14-hour flight from Seoul, South Korea. They’re in town to perform at KCON New York, a two-day celebration of Korean culture culminating in evening concerts at Madison Square Garden. It’s one of the many exciting opportunities they’ve earned since they debuted in March with their EP “Dream Chapter: Star.” The EP topped the charts in Korea and was number one on Billboard’s Emerging Artists and World Albums charts. At number 140, it was also the highest charting debut by an all-male K-pop group on the Billboard 200. The EP’s lead single “Crown” debuted at number one on Billboard’s World Digital Song Sales chart, and its music video was viewed more than 15 million times on YouTube in the 24 hours after its release. The group went on to perform a six-city debut showcase tour across the U.S. All this has happened in the past four months, and the success has set TXT apart as a group to watch.

They’re snacking on candy while we chat and Beomgyu contentedly munches on a piece flavored like one of his favorite summer treats, watermelon. Soobin, who sometimes giggles demurely behind his hand, tries very mild licorice, covered in chocolate. His eyes light up as he chews. “I love it!” he declares loudly, holding up the wrapper. Taehyun and Huening Kai burst out laughing at his reaction and Yeonjun sings “I love it,” a lyric from “Crown,” under his breath.

What else do they love? “We love to play board games,” says Huening Kai, and he and Yeonjun agree that Monopoly is the group favorite. Soobin perks up again. “And I love video games! Do you know AoS?” he asks, drawing a small “S” in the air with his finger. A quick Google search reveals that AoS is an acronym for Aeon of Strife, a fan-made map created within the game Starcraft, the extremely popular multiplayer online battle arena, or MOBA. All this to say that Soobin is more than a casual gamer.

Before debuting, all five members trained in dancing, singing, rapping, and other disciplines for at least three years under Big Hit Entertainment, the Korean company behind musical juggernauts BTS. Dream Chapter: Star was produced by some of the same talents that helped craft BTS’s hit music. The EP’s lyrics and imagery introduce a fictional world where the sudden growth of horns is used as a metaphor for the confusing, and sometimes scary, growing pains of adolescence. “Crown,” an exuberant, synthy pop smash, tells the story of a boy who, after meeting another boy with wings, learns to see his horns as something to be proud of, like a “crown on [his] head.” Fans think that the “boy with wings” is a reference to the alternate universe of BTS’s discography, where wings are a prominent trope, but that hasn’t been confirmed by Big Hit.
