🇰🇷 Park Seo-joon (Park Yong-kyu)

The 'Itaewon Class' lead whose Marvel cameo broke the Korean K-drama actor into the MCU

'Kill Me, Heal Me' • 'She Was Pretty' • 'What's Wrong with Secretary Kim' • 'Itaewon Class' • 'The Marvels'

On a back lot at Pinewood Studios outside London in the spring of 2022, a Korean actor walked onto a Marvel Studios soundstage for the first time, carrying nothing but a paperback English script and a thermos of cold-brewed coffee. Park Seo-joon, then thirty-three, had been cast as the prince of a fictional alien civilisation in 'The Marvels', the sequel to 'Captain Marvel'. He spoke little English. The dialogue coach told him to bring a thermos because Marvel days were long. He used it as a mug rest. He did not put the script down for the next three months.

Park Yong-kyu was born on 16 December 1988 in Seoul, the eldest of three brothers. He was an average student at Bongwon Elementary School and a frequently bored teenager at Geumho Senior High, where his only consistent academic enthusiasm was for English-language pop, which he listened to on a second-hand iPod nano he later credited with teaching him how to dance. He failed his first university entrance exam, retook it, and was admitted to the theatre and film department at Seoul Institute of the Arts.

He was scouted in 2008 after appearing in the music video for Bang Yong-guk's song 'I Remember' alongside a then-unknown actress named Suzy. His acting debut was a minor supporting role in the 2011 KBS drama 'Dream High 2'. He then served his mandatory military duty between 2008 and 2010 (he had enlisted before his acting debut), and resumed his career as Park Seo-joon — a stage name, like Gong Yoo's, suggested by his agency.

The breakthrough came in 2014 with the KBS family drama 'A Witch's Romance' and accelerated through three back-to-back hits: 'Kill Me, Heal Me' (2015), 'She Was Pretty' (2015) and 'Hwarang' (2016-17), the last of which paired him with a then twenty-three-year-old Park Hyung-sik and a pre-debut BTS member named Kim Tae-hyung. By the time he led the 2018 tvN romantic comedy 'What's Wrong with Secretary Kim', he was Korea's most reliable male romantic lead.

His career-defining role arrived in January 2020 with the JTBC drama 'Itaewon Class', adapted from a webtoon of the same name. He played Park Sae-ro-yi, a young ex-convict who opens a single bar in Seoul's Itaewon district and builds it into a multinational restaurant chain, all while pursuing an elaborate vendetta against the chaebol family that destroyed his father. The drama posted some of the highest cable ratings of the year and became one of Netflix's most-watched Korean titles in its first year of global K-drama distribution.

His film work, less prolific than his television output, has included Bong Joon-ho's 'Parasite' (2019), in which he played an unnamed friend who introduces the lead family to the wealthy household at the heart of the film. The role was small but consequential. Bong cast him personally, having seen his work on 'A Witch's Romance', and Park spent a single afternoon on set on what would become the most globally distributed Korean film ever made.

In 2022 Marvel Studios announced Park as the male lead of 'The Marvels', playing Prince Yan, the consort to Brie Larson's Carol Danvers. The film was released in November 2023. Critical reception was mixed, but Park's casting — taken without conventional Hollywood agent representation and largely on the strength of the Bong Joon-ho cameo — was widely treated as a structural moment in Korean actors' ability to break into the American studio system.

He continued in 2023 and 2024 with the historical-fantasy drama 'Gyeongseong Creature' on Netflix, set in 1945 colonial Korea, alongside Han So-hee. The series received a guaranteed two-season order and became one of Netflix's most-watched Korean originals in its release week.

He runs his own one-man entertainment label, Awesome Entertainment, in partnership with longtime manager Kim Jang-gyun. Friends describe him as the rare Korean actor who reads pre-purchase research reports for every endorsement deal his team brings him.

His personal life has remained, by Korean A-list standards, almost monastically private. He has never confirmed a public relationship, gives roughly one in-depth interview per project and spends most of his off-time, according to friends, on long-distance road cycling in Gangwon province. He has been the public face of the Korean cancer-charity Make-A-Wish Korea since 2017 and quietly underwrites scholarships at Seoul Institute of the Arts for first-generation theatre students from non-Seoul provinces. The combination of commercial reach and personal opacity has made him, by Hallyu industry consensus, one of the cleanest brand collaborators in the business — a reputation that has consistently translated into endorsement renewals across the Asian and European luxury sectors.

“I did not start acting because I dreamed of acting. I started because I was tired of failing.”
— Park Seo-joon, Cine21 interview
“Sae-ro-yi was harder than anything I'd played. He doesn't blink. He doesn't apologise. He doesn't smile easily. I had to unlearn most of myself.”

'What's Wrong with Secretary Kim' Trailer (tvN)

Park Seo-joon is the clearest case study of how a Korean television actor in the streaming era can leverage a single global-hit drama into Hollywood casting. His path from 'Itaewon Class' on Netflix to 'The Marvels' at Marvel Studios — within three years and without conventional American representation — established a new template for K-drama-to-MCU mobility.

Inside Korea, his 2020-23 run on 'Itaewon Class', 'Gyeongseong Creature' and 'Concrete Utopia' demonstrated an unusual willingness to take roles that distort the romantic-lead archetype that initially made him bankable. The choices broadened the range of what a male romantic-lead actor in his thirties is expected to do, and pulled the rest of his cohort with him.
