Sourcebook
Intro
Tomorrow X Together (TXT) is a revolutionary five-member South Korean boy band under BigHit Music that serves as the definitive vanguard of K-pop’s fourth generation. Formed by the same visionary agency behind global icons BTS, TXT was designed from day one to break industry standards. Since their massive March 4, 2019 debut, they have entirely eschewed traditional K-pop lane boundaries—rejecting fixed vocal or rap titles, experimenting relentlessly with rock, pop, and electronic subgenres, and implementing a profound, multi-year narrative universe centered entirely on the raw, painful, and beautiful realities of growing up.
Rather than coasting on the fame of their corporate seniors, TXT established an entirely independent musical footprint. They became the first K-pop act to headline Lollapalooza, a multi-million-selling force on the Billboard 200, and a rare group where all five members function seamlessly as visual centers, principal dancers, and distinct vocalists. The story takes place at the dormitory.
