Han Hyun Uk, known mononymously as Hyunuk, is a South Korean singer, dancer, and former member of UNIT BLACK (유닛 블랙) and SKYE (스카이; previously known as IN2IT (인투잇)). He graduated from Hwahong High School and later obtained a bachelor's degree in Industrial Information System Engineering from Chonbuk National University.

He made his debut in 2017 as UNIT BLACK's lead vocalist with their 1st single "Steal Your Heart." The group was the first promotional unit formed after the conclusion of the singing survival show BOYS24 (소년24). However, under their agreement, they were only active for 4 months and disbanded in August of the same year.

In October 2017, he re-debuted as IN2IT's main vocalist with their 1st EP "Carpe Diem."

Due to the COVID-19 pandemic, the members decided to enlist in their mandatory military service and, at the same time, ended their contracts with MMO Entertainment (MMO엔터테인먼트), electing to become independent.

He was discharged on June 20, 2022 and founded First Entertainment alongside his group mates. In March 2023, the group rebranded under their new name, SKYE, and released their first single, "A New Beginning".

In November 2025, the group announced an indefinite suspension of activities following their last scheduled concert in December. All members will now focus on the individual work, and no further plans for them to appear as SKYE are scheduled.
