Jungsu
Jungsu (정수) is the keyboardist and main vocalist of Xdinary Heroes (엑스디너리 히어로즈), the six-member rock band under JYP Entertainment's Studio J sub-label. Born Kim Jung-su on June 26, 2001, he brings a melodic foundation to the group's hard rock and alternative sound.
Debuting on December 6, 2021 with "Happy Death Day", Jungsu immediately distinguished himself as the member bridging keyboard-driven arrangements with the full live instrumentation that defines Xdinary Heroes' identity. As main vocalist, he carries much of the group's emotional weight while managing the tonal range demanded by tracks spanning from driving rock to softer introspective cuts.
Across eight mini albums and one full-length record, Xdinary Heroes have built a catalog that is entirely self-written and self-produced. Jungsu's contributions as both performer and co-writer have been central to the band achieving this benchmark, rare in the JYP ecosystem and K-pop more broadly.
