They Dated Publicly for 13 Years Turns Out Koo Kyo-hwan and Lee Ok-seop Were Already Married

For 13 years, they were Korean cinema’s most beloved open secret an actor and a director who met as film students, built a body of work together, and never seemed to need a label for what they were. Now we know the label existed all along. Koo Kyo-hwan (구교환) and director Lee Ok-seop (이옥섭) have been legally married since 2022, their agency confirmed on October 1 a revelation that lands not as scandal, but as the quietest possible exclamation point on one of the industry’s most admired partnerships.

A Confirmation, Not an Announcement

The news broke through Dispatch, the outlet famous for surfacing Korean celebrity relationships, and was swiftly confirmed by Koo Kyo-hwan’s agency, Namoo Actors. Koo Kyo-hwan and director Lee Ok-seop did register their marriage in 2022 and formed a marital bond,” the agency stated plainly.

There was no wedding spread, no staged photo call, no carefully timed press release. By the time the public learned of it, the couple was already four years into married life. That restraint is entirely on brand. The pair’s romance only became public knowledge in 2020, when an exclusive report revealed what people in the film world had long understood. They had, in fact, been together since 2013 fellow alumni of the Seoul Institute of the Arts, where their creative and personal lives first intertwined.

Thirteen Years, Built One Project at a Time

What makes this couple distinct isn’t the secrecy it’s the sheer volume of work they’ve made side by side. Long before the marriage registration, Koo Kyo-hwan and Lee were collaborators in the truest sense, co-creating a string of short films that doubled as a shared artistic language: Fourth-Year Student Bo-kyung, Fly to the Sky, Girls on Top, Maggie, and Your Country, among others.

Maggie (2018) is the keystone of that collaboration. Directed by Lee and featuring Koo Kyo-hwan, the surreal dramedy which opens with a hospital in uproar over a scandalous X-ray became a festival favorite and a calling card for both. It signaled Lee as one of the most inventive voices of her generation and gave Koo Kyo-hwan a showcase for the offbeat, live-wire presence that would soon define his career. The couple also co-manages 2x9HD, a YouTube channel where they’ve long shared their experiments and collaborations directly with fans a reminder that their partnership has always been as public creatively as it was private personally.

The Breakout That Made Him a Household Name

Koo Kyo-hwan’s trajectory is a case study in the slow-burn ascent. He first drew notice in independent films like Jane (2016) and Maggie (2018), the kind of roles that earn an actor a devoted cult following before mainstream recognition catches up. Then came the one-two punch of 2020 and 2021: Peninsula, the big-budget sequel to Train to Busan, and Escape from Mogadishu, Ryoo Seung-wan’s acclaimed political thriller, in which Koo Kyo-hwan played a North Korean hardliner willing to risk death rather than ask his southern counterparts for help.

But it was Netflix’s D.P. (2021–2023) that cemented his status. As a military deserter-hunter navigating the brutal realities of conscription, Koo Kyo-hwan delivered a performance that resonated far beyond Korea, turning him into one of the country’s most sought-after character actors and a familiar face to the platform’s global audience. His appeal has always been his unpredictability he can be menacing, comic, and quietly heartbreaking, sometimes within the same scene.

A Partnership That Points Forward

In its statement, Namoo Actors leaned into warmth rather than spectacle. “We ask for warm blessings and support for the future of these two, who have always been a steadfast source of strength for one another,” the agency said, adding that “Koo Kyo-hwan and director Lee Ok-seop will continue to work hard to greet audiences with good work, each in their own place.”

That framing matters. In an industry where private lives are often weaponized, this couple has managed to keep theirs on their own terms collaborators first, spouses quietly second, and never fodder for a narrative they didn’t choose. The marriage reveal doesn’t change the story so much as confirm what their fifteen years of shared work already told us.

And the work keeps coming. Koo Kyo-hwan appeared in The Resurrected: The Red (부활남: 더 레드), which opened September 30, and he returns next month in Heavy Snow (폭설). For a performer who built his name on refusing the obvious, there’s a certain poetry in learning that his biggest personal milestone happened years ago and that, true to form, he simply let the work speak until the moment was right.
