Do Mo-se is a Korean AV actor who debuted in 2015 in the movie Stormy Affair. In 2012, he participated in Season 2 of the reality television show Korea's Got Talent as 'Little Rain'. He was often casted in adult films due to his various charms, including his handsome appearance, tall height, well-built body, and decent acting skills. In August 2019, he announced his retirement for the reason that his religious profession as a Protestant doesn't suit his sentiment of being an adult actor and for the sake of his girlfriend. He also said that he plans to live his life as a writer and published his first erotic essay with the Korean title 스물 아홉, 에로영화 찍으러. After almost five years, he comes out of retirement and becomes active again in the AV industry by the end of 2024.
