Park studied filmmaking at the Seoul Institute of the Arts after his military service. He dropped out before the end of his freshman year after feeling overwhelmed by the responsibilities of film directing and not being talented enough. However, he decided to give acting a try as he enjoyed playing bit roles in the movies of his classmates.
He had his first lead role in The Boys Who Cried Wolf (2016) which won Best Actor at the 4th Wildflower Film Awards in 2017. He also won the Actor of the Year Award at the 22nd Busan International Film Festival for the indie film Hit the Night (2017) by director Jeong Ga-young.
