Lee Jun-young, born on January 22, 1997, is a South Korean singer, rapper, and actor who has carved a distinctive path in the entertainment industry through his remarkable versatility and bold artistic choices. Initially rising to fame as a member of the boy band U-KISS in 2014, he later cemented his place in the music world by winning the survival program The Unit (2017–18), which led to his role as the center and main vocalist of the project group UNB. However, it is his acting career that has truly set him apart, earning him widespread acclaim for his compelling performances in a series of critically acclaimed productions, including the Netflix series D.P. (2021), Mask Girl (2023), When Life Gives You Tangerines (2025), and Weak Hero Class 2 (2025).
Lee’s journey into the spotlight began in his teenage years when he joined U-KISS, a group that had already established a dedicated fanbase. Though his time with the group provided valuable experience in performance and stagecraft, it was his participation in The Unit that proved transformative. The show, which aimed to give second-chance opportunities to idol trainees and active idols, showcased Lee’s vocal prowess and charisma, ultimately earning him a spot in UNB. The project group enjoyed moderate success before disbanding, but the exposure opened new doors for Lee, particularly in acting.
Transitioning from music to acting, Lee quickly demonstrated a natural affinity for the craft. His breakout role came in the Netflix series D.P., based on the webtoon about military desertion police officers. Playing a soldier grappling with the harsh realities of military life, Lee delivered a nuanced performance that resonated with audiences and critics alike, establishing him as a serious actor. He followed this with a role in Mask Girl, a dark comedy-thriller about an ordinary woman with a secret double life, where his portrayal of a complex character further highlighted his range. His ability to inhabit unconventional and challenging roles has earned him the nickname "the acting god" among fans and industry observers, who praise his fearless approach to selecting projects that defy typical idol-actor expectations.
Lee’s career continued to ascend with his involvement in When Life Gives You Tangerines, a highly anticipated drama that explores themes of resilience and love, and Weak Hero Class 2, the sequel to the hit action series about high school violence. These projects have solidified his reputation as one of the most interesting and unpredictable actors of his generation. Beyond acting and music, Lee has proven to be a true multi-hyphenate. He has participated in musical theatre, showcasing his singing and dancing abilities on stage, and has also engaged in dance battles, variety programs, art exhibitions, and hosting activities. This wide-ranging skill set has led some to describe him as a "hexagonal trendsetter," a term used in South Korea to denote someone who excels in multiple fields like the six sides of a hexagon.
Throughout his career, Lee Jun-young has consistently defied easy categorization. He has successfully navigated the transition from idol to respected actor without abandoning his musical roots, and his willingness to take on diverse and often unconventional roles has set him apart from his peers. As he continues to expand his filmography and explore new creative avenues, Lee remains a dynamic force in the Korean entertainment landscape, admired for his dedication, talent, and fearless pursuit of artistic growth.
