ONE PACT is a five-member South Korean boy group managed by ARMADA Entertainment. The lineup consists of JONGWOO, JAY CHANG, SEONGMIN, TAG and YEDAM. Its name combines ONE and IMPACT, reflecting the idea that five individual histories can create something more powerful together.

The group debuted on November 30, 2023, with the mini album Moment and its title track Must Be Nice. Before the debut, the members had already appeared in televised auditions or promoted in other acts: JONGWOO came from Black Level, SEONGMIN from TO1, TAG from Ciipher, while JAY CHANG and YEDAM were also known from survival programmes. That experience distinguishes ONE PACT from a conventional first-time trainee lineup.

ONE PACT places an unusual level of emphasis on making its own music. TAG has been heavily involved in the group’s composition, lyric writing and production, and JONGWOO has directed and edited a number of performance and music videos. The members have also contributed to choreography. Across PARADOXX, fallIn’, PINK CRUSH and ONE FACT, the group has moved between aggressive hip-hop, melodic R&B, ballads and brighter pop.

ONE FACT in July 2025 brought five member solo recordings together with the group track YES, NO, MAYBE. The individual songs highlight different musical preferences, but they were released within ONE PACT’s project rather than as five independent solo albums. Two members have broader solo discographies: JAY CHANG released music under his own name before and after the group’s debut, while TAG released solo material as RAPH4EL in 2026.

In February 2026 the group introduced its first EP 1’ONLY, led by the high-energy SANE. July’s two-track digital single TUNED IN brought all five members together on U so hot and Whts yo name. TAG took the production lead, with JAY CHANG also contributing lyrics. The five completed a 14-city tour across the United States, Latin America and Canada in September 2026, following their earlier European dates. The official fandom name is &HEART (&♡).
