Early Life and Education

Woo Sung-hyun was born on November 25, 1991, in Danville, California, and grew up in the San Francisco Bay Area under the care of Mr. and Mrs. Woo. His mother was a former fashion model in South Korea, while his father played piano and guitar, and his paternal uncle, Emmanuel Woo, was a classical opera singer in Germany.

Raised with his elder sister, Deanna, he developed an early interest in music, refining his vocal and guitar skills during his school years. He attended Monte Vista High School in Danville, where he balanced academics with local musical activities.

At age fifteen, a successful summer talent audition led to his relocation to Seoul, South Korea, for professional training. He is of South Korean ethnic heritage and practices Christianity.

Career

Kevin Woo initiated his professional musical journey in 2006, securing a vital early entry point as a member of the project boy group XING before capturing massive mainstream attention by debuting as a main vocalist for the K-pop group U-KISS in 2008.

Facing the grueling physical and competitive pressures of the South Korean music industry, he weathered intense schedules to help propel the group to global prominence with massive international hit singles like "Man Man Ha Ni” and "Bingeul Bingeul.” His distinctive, smooth vocal delivery and flawless English fluency established him as a premier asset for the group’s global promotions, allowing them to anchor major stadium tours across Asia, Latin America, and Europe.

His career experienced profound growth and a structural redirection when he transitioned into television broadcasting, capturing a massive international fan base as the long-running main co-host of Arirang TV’s landmark interactive music program After School Club. Serving as a vital cultural bridge between global Hallyu fans and active K-pop idols, his charismatic, bilingual presentation style permanently etched his face into contemporary pop culture history.

Following his formal departure from U-KISS in 2017, he successfully pivoted toward a solo trajectory, signing major management deals to drop English and Japanese solo singles such as “Ride Along” and “Got It,” while aggressively re-establishing his footprint in the United States.

In recent years, he has completely redefined his artistic legacy by successfully crossing over into premier theatrical and Hollywood productions, making his official Broadway debut in the K-pop-inspired stage production KPOP in New York City. His global industry influence expanded exponentially when he provided the premier singing voice for the character Mystery Saja, a member of the fictional boy band The Saja Boys, in Netflix’s blockbuster animated musical fantasy KPop Demon Hunters.

The film’s record-shattering viewership paired with his subsequent high-profile casting in Anderson .Paak‘s feature directorial debut K-Pops completely solidified his transition into Hollywood, culminating in a worldwide representation contract with United Talent Agency (UTA). He has sustained this incredible momentum into the mid-2026 media era, headlining major live U.S. concert showcases and debuting in U-KISS’s new global sub-unit, UX1.
