Do Hayoon (도하윤)

Park Ji-hoon — known professionally as Do Hayoon — has spent nearly a decade moving between K-pop stages and television screens with a consistency that has made him one of the more quietly durable figures to emerge from the idol-competition format. Originally a member of the project group Wanna One, formed through Mnet's *Produce 101 Season 2*, he has since built a parallel acting career substantial enough to earn him the designation of "ten million actor" — a reference to his film *The Man Who Lived with the King* drawing cumulative admissions past the ten-million mark — while continuing to record and perform as a member of both Clear:I and ILUV (아이러브).

From Produce to Wanna One

Park Ji-hoon's name first registered widely during his run on *Produce 101 Season 2*, where he placed in the group that formed Wanna One. The nine-year gap between that debut and the 2026 Mnet Plus reality retrospective *WANNA ONE GO: Back to Base* — in which surviving members undertook fan-requested challenges including a zero-gravity light aircraft test — speaks to the unusual longevity of that group's hold on its fanbase, known as Wannables. A 2026 poll naming Ha Sung-woon first and Park Ji-hoon second among male singers fans wished to share a rainy-day umbrella with was attributed, in coverage, to the aftereffects of Wanna One's reunion activity.

Music & Group Activity

Alongside his acting work, Park Ji-hoon has remained active in the idol sphere as a member of both Clear:I and ILUV (아이러브). The overlap between an established solo profile and concurrent group memberships places him in a category of performers whose idol identity remains live rather than archival. His fan concert *2026 Park Ji-hoon Fan-Con [RE(Reflect)]*, held in 2026 after a seven-year gap between fan concerts, sold out both dates. In remarks at the event, he spoke directly to his fandom May, a name that has followed him since his Wanna One era.

Acting Career

The acting dimension of Park Ji-hoon's career has become, by 2026, at least equal in visibility to his music work. *The Man Who Lived with the King* — a film in which he portrayed the historical figure Danjong — crossed ten million cinema admissions, placing him in a commercially selective tier of Korean film performers. The TVING original drama *The Legend of the Cook Soldier*, in which he stars as Kang Sung-jae, a soldier whose skills in a military kitchen become the engine of a comedy-fantasy-growth narrative, followed within roughly three months of that film milestone.

The drama's ratings trajectory was notable: viewership climbed from 1.7 percent at launch to 7.3 percent and eventually to a peak of 10.8 percent by its sixth episode, surpassing several competing titles. Critical commentary framed the performance as a confirmation of range — Park Ji-hoon's portrayal was described in coverage as moving fluidly between comedy, including improvised scenes that reportedly caused extended laughter on set, and more grounded dramatic beats. Behind-the-scenes interviews saw him discuss his approach in terms that pushed back against industry self-promotion; he cited a nine-year effort to maintain his initial mindset and described finding self-congratulatory behavior unappealing.

His episode of tvN's long-running variety program *You Quiz on the Block* had previously held the show's highest ratings for the 2025–2026 period before being surpassed by an episode featuring NVIDIA founder Jensen Huang — a footnote that nonetheless placed his individual episode in measurable company.

Standing

A 2026 industry survey of first-half drama performances grouped Park Ji-hoon alongside Shin Hye-sun and Moon Sang-min as actors who had successfully headlined two consecutive projects in the same period, each consolidating or expanding their critical standing. For Park Ji-hoon specifically, the framing was one of expanded presence — a performer whose idol origins have not functioned as a ceiling. With a reported 16.88 million fans and sold-out fan events, the audience that followed him out of the competition-show format has remained engaged across the shift into film and drama.
