Park Hyung Sik is a former member of the now-defunct South Korean boyband ZE:A and its subgroup ZE:A Five, managed by Star Empire Entertainment. In April 2017, Park officially signed with United Artists Agency (UAA) after deciding not to renew with his former agency.

He is also known for his starring roles in television dramas Hwarang: The Poet Warrior Youth (2016-2017), Strong Woman Do Bong Soon (2017), and Suits (2018).
