On December 12, 2016, it was announced that he and Kichun left the group. He soon joined JN Entertainment, a small company started by Kichun where he made his solo debut with a future bass and hiphop single "Push & Pull". In 2017, Z-uK became a contestant on KBS 2TV's idol rebooting show The Unit.
He was eliminated in episode 8 after achieving 56th place. In early 2018, Z-uK came back with a R&B style single called "Dreaming". Later that year he came back again with a hiphop single called "Hot Sauce".
In late April of 2020, a show called the SIGMA PROJECT began in which Z-uK formed the Korean-Japanese boy group SIGMA. On March 22, 2022, the official SNS accounts for the upcoming group WE:A opened with their biographies for each platform including five names, with Z-uK being one of those members. On December 25, 2025, Z-uK announced that he would release his first mini album, Z on January 11, 2026.
However, on January 7, 2026, it was announced again that the mini album would be released on January 16, 2026.
