Si Woo

Si Woo is a South Korean screen performer known through a large volume of acting credits in Korean low-budget and adult-oriented features released from the late 2010s into the mid-2020s. Public biographical information about him is limited: The Movie Database lists him as a male actor, gives Korean and Chinese name variants including 시우, 김시우, 주향윤, Joo Hyang-yoon and 时宇, and does not publish a birth date or birthplace. Because independent profile material is scarce, the clearest public record of his career is his filmography.

Si Woo's listed credits begin in 2017, a year in which he appeared in titles such as Friend Couples: Swapping, My Girlfriend's Mother, Swapping Wives and A Kind Affair. TMDB credits identify named roles for several early parts, including Tae-gyoon in Friend Couples: Swapping and Kyeong-joon in My Girlfriend's Mother. His work continued steadily through 2019 and 2020, with credits including Mother's Lover 3, The First Time 3, Young Aunt 3, Sisters: Memories of Confinement, Big Breasts Sister, Wife for Rent, Taming The Younger Sister-in-Law and The Girl Who Listens to the Witch's Heart.

From 2021 onward, Si Woo remained active across many short-form or direct-to-video-style releases. His listed roles include Young Tae in Office Sex 2021, Yeong Tae in Idol Seungha's R-Rated Film Shooting, Seung-mo in 6th Period Sex Class, Hyeon-goo in 2-on-1 Business Trip Massage 2, Hyeok-goo in Masseuse Ye-ra's Amazing Hand Technique: Two Feet at Once, Do-joon in Military Woman, and Na-moo in Sex Bot Fairy. The body of public credits points to a performer who worked frequently in a specialized segment of the Korean screen market rather than in broadly publicized mainstream film and television.
