He made his debut in April 2018 as the group's lead vocalist, rapper and visual with their first mini-album, "Twenty's Noir". However, LUK Factory (럭팩토리; formerly known as IONE Entertainment) mishandled the group's management, which led to several arguments with the members.
On August 19, 2022, he was found guilty of breaking and entering, assaulting, and threatening with a deadly weapon. He had been harassing his ex-girlfriend for two weeks before the incident took place. He was found guilty and sentenced to two years probation (which becomes one year in prison if he commits a similar crime) and 80 hours of community service.
It was never announced, but it is assumed NOIR quietly disbanded in mid-2023. He is out of the entertainment industry.
