Lee was born on June 29, 1979 in Songhyeon-dong,
Dalseo District,
Daegu, South Korea. The turning point in his life came a week before his military enlistment, when he had a farewell party and got into a car accident that required major surgery. As a result, he was exempted from military service. Despite being exempt, he lost interest in his studies and wandered for a while, spending his days playing guitar, singing, and drinking. During this time, he happened to see a poster for a children's theatre company in Daegu and out of curiosity, he visited the theatre company. Lee worked as the youngest member of the Daegu theatre company "Onnuri" for approximately 2 years and 6 months. Instead of being an actor, his role within the troupe involved tasks such as cleaning, cooking, and putting up posters. Lee independently studied and followed
Stanislavsky's book ''Actor's Class''. == Career ==
