Everyone around me teased that I was awkward and hadn’t gotten used to things yet.” Park plays the role of Jung Yi-hyun, a police detective and Sae-bom’s lifelong friend.

The actor gained notoriety as K-drama’s most swoon-worthy boyfriend in Strong Girl Bong-soon. Park also starred alongside actor Park Seo-joon in the coming-of-age historical K-drama, Hwarang: The Poet Warrior Youth.
