How Park Ji-hoon Became K-Drama's Go-To Webtoon Adaptation Actor

Park Ji-hoon is making his case again. After breaking into Korea's exclusive "10-million-viewer actor" club this year with the feature film "The Man Who Lives With the King" (Wanggwa Saneun Namja), he has made a swift return to the small screen with the webtoon-based drama "The Legend of Kitchen Soldier" (Chwisabyeong Jeonseori Doeda). With the early audience response proving exceptionally strong, Park is further solidifying his reputation for transforming flat, two-dimensional webtoon characters into layered, living individuals on screen.

"The Legend of Kitchen Soldier" ranked No. 1 in paid subscription contributions on TVING during its debut week. Notably, it secured the highest week-one subscription metrics of any TVING original drama released over the past three years. At the absolute center of this commercial momentum is Park.

Park has navigated a demanding string of webtoon adaptations throughout his career, consistently replicating the distinct visual profile and emotional core of the source material to win over even the most critical fans. Here is a look at the definitive filmography that has established him as K-drama’s premier actor for webtoon-to-screen translations.

"Love Revolution" (Yeonae Hyeokmyeong), 2020 — Wavve, TVING

"Love Revolution" is a nostalgic teen romantic comedy centering on the chaotic first loves and tight-knit friendships of students at Jeongbo High School. Park portrayed Gong Ju-young, a fiercely loyal and innocent high schooler who throws himself headfirst into romance without a second thought.

He pulled off the character's signature bowl cut hairstyle without a hint of visual awkwardness, instantly clearing the high aesthetic bar set by the original artwork. The cartoonish gags and exaggerated displays of affection, which could easily feel cringeworthy in live action, were effectively grounded by Park's harmless, disarming charm. He preserved the inherent warmth of the webtoon, carving out a distinct lane for himself as a refreshing romantic lead.

The "Weak Hero" Series (Yakhan Yeongung), 2022 and 2025 — Netflix

This gritty franchise served as a major turning point that redefined Park as a serious actor. The "Weak Hero" series follows Yeon Si-eun, a physically slight, top-of-the-class student who utilizes cold intellect and psychological strategy rather than brute strength to dismantle systemic school violence.

Behind his small frame and quiet exterior, Park projected a chilling, calculated intensity through deeply restrained performance work. His execution of controlled emotional breakdowns and brutal, analytical action sequences captured the heavy psychological wounds of the character, firmly establishing Park as a performer capable of immense dramatic weight.

"The Legend of Kitchen Soldier" (Chwisabyeong Jeonseori Doeda), 2026 — TVING

The series follows Private Kang Sung-jae (played by Park) as he charts a grueling trajectory to become a legendary military cook. Having supported his family through difficult socioeconomic circumstances alongside his father, Kang enlists in the military immediately following his father's sudden passing and is subsequently assigned to the culinary division.

Park transitions seamlessly between the suffocating pressures of institutional military life and the genuine passion that ignites within his new role, giving narrative weight to a premise that could otherwise veer into fantasy. The portrait of a young man navigating a stalled life through cooking, validating his own self-worth in the process, has deeply resonated with contemporary viewers. Watching a clumsy conscript who once flinched at the glares of senior soldiers gradually win over a hardened room of officers and peers—one meticulously crafted dish at a time—delivers a highly satisfying emotional payoff.

Webtoon-based dramas inherently cut both ways. A built-in readership guarantees substantial early buzz, but a poor alignment with beloved source characters can trigger intense backlash from those same loyal readers.

From the soft-hearted Gong Ju-young in "Love Revolution," to the icy, strategic Yeon Si-eun in "Weak Hero," to the underdog conscript Kang Sung-jae in "The Legend of Kitchen Soldier" currently airing, Park has kept the distinct appeal of each original creation intact while delivering a fully realized live-action counterpart. He systematically bridges the "adaptation gap" with precise character interpretation and solid acting fundamentals. How he continues to develop Kang’s narrative, as the character begins carving out his own definitive path as a master kitchen soldier, remains highly anticipated.
