IDID is the second K-pop group to debut under STARSHIP Entertainment after KiiiKiii.
In July 2024, STARSHIP (IVE, MONSTA X, CRAVITY) unveiled its plans to launch a new boy group through a pre-debut survival program titled “NewKids on the STARSHIP.”
This project later evolved into the official YouTube series “Debut’s Plan,” which aired from March 14 to May 4, 2025. The show followed Starship trainees as they competed for a place in the company’s first new boy group in five years.
After weeks of intense performances, evaluations, and eliminations, the final lineup was revealed on May 4, 2025, along with the group’s official name: IDID. Meaning “I did it,” the name reflects the members’ journey, growth, and determination to debut.
Originally, eight members were selected, but Park Junhwan left the group on June 2, 2025, due to psychological stress caused by false online rumors.
