NCT JNJM is a South Korean musical duo formed by SM Entertainment, comprising Jeno and Jaemin, who were born on 26 January 2026 in Seoul. The pair began training with SM Entertainment after being cast in the baseball‑themed short‑form drama Wind Up in 2025, which led to their official debut as a sub‑unit of NCT. On 23 February 2026, they released their debut extended play BOTH SIDES, featuring the lead single "Both Sides", which debuted at Number one on the Korean Digital Chart with 444,494 downloads in its first week. The duo’s musical identity centers on duality, blending Jeno’s powerful performance with Jaemin’s sophisticated charm, and the EP also charted at Number two on the Billboard World Albums Chart. Subsequent releases include the single "7th Sense" and "Without You", both of which entered the Top 20 of the Korean Gaon Chart. NCT JNJM embarked on a national promotional tour in March 2026, performing on major music programs such as Music Bank and Inkigayo. The duo’s work received critical acclaim, earning a nomination for Best New Artist at the 2026 Korean Music Awards. Their debut EP remains a commercial benchmark for SM Entertainment’s sub‑unit strategy, and BOTH SIDES continues to rank among the top‑selling K‑pop releases of 2026.
