Sungsub

Sungsub debuted with the boy group N. CUS on August 27, 2019. Unfortunately, on January 5, 2022, fellow member Hojin revealed that the 8 out of 9 of the current members of N.

CUS had terminated their contract with Kyuri, leaving them presumably disbanded. On February 3, 2023, he was revealed through poster alongside the fellow members Seo Seokjin, Euntaek, Seungyong, and Hyeonmin, with a group new name, NCUS, showing also their March performance dates at K-Square in Tokyo, Japan hinting that the group would be active again.
