Park Hyung-sik made his official debut in 2010 as a member of the K-pop boy group ZE:A. While he initially gained fame through music and variety shows—earning the beloved nickname "Baby Soldier" on Real Men—his transition into acting was seamless. In the early 2010s, he began building his filmography with supporting roles in dramas like Dummy Mommy (2012), where he played an indie band vocalist, and Nine (2013), where his performance as the younger version of the protagonist proved his potential as a serious actor.
One of his most iconic early roles was in the legendary SBS series The Heirs (2013). He played Jo Myung-soo, the playful and wealthy heir to a top law firm. Although he was part of a star-studded cast including Lee Min-ho and Park Shin-hye, his bright and witty energy made him a fan favorite. Following this, he starred in the family drama What Happens to My Family? (2014), portraying the youngest son, Cha Dal-bong. His relatable performance earned him the Best New Actor award at the KBS Drama Awards, solidifying his status as a rising star.
His career reached a turning point with High Society (2015), where he played Yoo Chang-soo, a charismatic third-generation chaebol. This role showcased his ability to lead a romance with depth. He then challenged himself in the historical drama Hwarang: The Poet Warrior Youth (2016), playing a faceless king with a lonely soul, which allowed him to display a more mature and regal side.
In 2017, Park Hyung-sik reached global stardom through Strong Girl Bong-soon. As the charming CEO Ahn Min-hyuk, he created one of the most beloved romantic comedy characters in K-drama history. His incredible chemistry with co-star Park Bo-young remains a hot topic among fans worldwide. After his military discharge, he made a powerful return in Happiness (2021), a high-stakes thriller where he played a smart and protective detective during a viral outbreak.
Continuing his streak of successful projects, he starred in the historical mystery Our Blooming Youth (2023) as a cursed Crown Prince. In 2024, he reunited with Park Shin-hye after eleven years in the healing medical drama Doctor Slump. He played Yeo Jeong-woo, a top plastic surgeon who falls into a slump, delivering a performance that perfectly balanced comedy and emotional vulnerability.
Not many people recognize Park Hyung-sik that he was shown in The Heirs (2013). At the time, he was actively promoting as a member of the K-pop group ZE:A, and this role played a crucial part in establishing his reputation as a "versatile idol-turned-actor." Viewers can still revisit this drama to see his youthful, fresh-faced charm that contrasts beautifully with his more mature roles today.
1. Jo Myung-soo, the Ultimate "Mood Maker": Park Hyung-sik portrayed Jo Myung-soo, the playful and wealthy heir to "Seungri," South Korea’s top law firm. Unlike his peers who were burdened by corporate succession and family politics, Myung-soo had zero interest in studying or power struggles. He was the quintessential "mood maker" of the elite Jeguk High School. Fans remember him most for his signature hobby: carrying a high-end camera everywhere to snap candid photos of his friends, capturing the fleeting moments of their turbulent teenage years.
2. On-Screen Dynamic with Park Shin-hye: In the drama, Park Hyung-sik and Park Shin-hye (who played Cha Eun-sang) were classmates at Jeguk High School. While Eun-sang entered the school under a "social welfare" scholarship, Myung-soo belonged to the "management succession" group—the highest tier of the school's rigid social hierarchy. Despite the difference in their backgrounds, Myung-soo was a constant presence in her school life. He was often seen hanging out with his close-knit circle, including Choi Young-do (Kim Woo-bin) and Lee Bo-na (Krystal Jung), frequently circling around Eun-sang with his witty remarks and infectious energy.
3. Key Locations and Recurring Presence: As a supporting character, Park Hyung-sik appeared consistently from the very first episode to the finale. He was a staple in scenes featuring the school’s hallways and the characters' exclusive hideouts. Notably, Jo Myung-soo’s private studio served as a major setting for the drama, acting as a sanctuary where the main leads often gathered to share their secrets and emotions.
The recent success of Doctor Slump (2024) has brought these The Heirs memories back into the spotlight. It marked the first time Park Hyung-sik and Park Shin-hye reunited on screen in approximately 11 years. The transition from playing high school classmates in 2013 to portraying elite doctors navigating a life "slump" as adults in 2024 has been a nostalgic journey for fans. Seeing the two stars grow from "The Heirs" to "The Doctors" adds a poignant layer of reality to their on-screen chemistry, making their reunion feel like a celebration of their decade-long careers.
Since 2025, Park Hyung-sik has boldly expanded his acting range into darker and more intense genres, proving his versatility beyond romantic comedies. His most significant recent achievement came with the SBS revenge drama "Treasure Island" (also known as Buried Hearts).
In this series, Park delivered a powerhouse performance as Seo Dong-ju, an ambitious man who hacks into a 2 trillion won political slush fund to take down the absolute evil that destroyed his life. His portrayal of a cold, calculating character seeking vengeance was both a critical and commercial success, reaching a peak viewership rating of 15.4%. For this career-defining role, Park Hyung-sik was honored with the Top Excellence Award (Genre/Action Miniseries) at the 2025 SBS Drama Awards held on December 31.
Following this success, Park made a daring move by taking on his first-ever major villain role in the Disney+ original series "Twelve," which aired from August to September 2025. Playing Ogui, a malevolent crow spirit, he showcased a chilling charisma in a fierce battle against the zodiac guardians led by Ma Dong-seok.
As of early 2026, Park Hyung-sik continues to remain in the spotlight. Just recently, on February 8, 2026, he was seen enjoying his personal time with long-time friend V from BTS, showing that he maintains a healthy balance between his demanding career and personal life. Fans are now eagerly looking forward to his next romantic comedy, "Proper Romance" (working title), where he will reunite with his Doctor Slump co-star Yoon Sang-hyeon later this year.
