Kim Hyun Soo, known mononymously as Hyunsoo, is a South Korean singer, dancer and former member of D1CE (디원스; pronounced "The Once"). He graduated from Daeryun High School and later attended the Applied Music program at Kyunghee Cyber University but dropped out. He is now enrolled in the K-Pop program at Hanyang University.

He was introduced as part of the pre-debut group HNB and was one of the 5 trainees selected to debut. Before joining the group, he formed a sub-unit with Woo Jin Young and promoted together for a while, releasing their first mini-album, "Present", in June 2018.

The group's agency, Dreamcatcher Company (드림캐쳐 컴퍼니, previously known as HappyFace Entertainment), set a subsidiary label for the selected members and asked the public to vote for the group's name. After several days, the name D1CE was chosen, and D1CE Entertainment was formally created.

He made his debut in 2019 as the group's lead vocalist and rapper with their first EP "Wake Up: Roll the World." They released a few single albums and digital singles until early-2021 when the group went on an indefinite hiatus.

He enlisted for his mandatory military service on March 21, 2022 and was discharged on September 20. 2023. However, all the members contracts expired 8 months earlier and the company decided not to renew them, effectively disbanding the group. No information regarding his current or future plans has been revealed.
