Lee Sang-yi

Few actors have bridged musical theater, ensemble K-drama, and internet-native variety culture as fluidly as Lee Sang-yi (이상이). Born November 27, 1991, in Ansan, Gyeonggi Province, he graduated from Korea National University of Arts' School of Drama before debuting on stage in the musical Grease in 2014. Steady work in theater and ensemble TV roles followed, but it was his warm, scene-stealing turn in Hometown Cha-Cha-Cha (2021) and the period melodrama Youth of May (2021) that earned him a devoted following. He escalated from fan-favourite to top-billed with the Netflix action thriller Bloodhounds (2023), playing a former marine who takes on loan sharks in kinetic, physically demanding fight sequences. In 2025 he co-starred with Park Bo-gum in the action-comedy Good Boy, playing a fencer-turned-police recruit. Parallel to his acting career, Lee became a member of MSG Wannabe, the viral all-actor vocal group born from MBC, whose emotional ballad performances made them one of Korea's most talked-about pop acts of 2021. Managed by Good Friends Company, he counts more than 2 million Instagram followers.
