South Korean actor Jang Dong-yoon is set to marry actress Kim Seung-yoon in October 2026, bringing an unexpected new chapter to a relationship the pair kept away from the public eye for years.
The The Tale of Nokdu actor personally announced the news on August 25, 2026, sharing a handwritten letter with fans. His agency, BH Entertainment, subsequently confirmed that the couple will hold a small wedding ceremony attended by their immediate families.
The announcement surprised many fans because Jang and Kim had maintained an unusually private relationship. Their professional connection, however, goes back several years.
Who Is Kim?
Kim Seung-yoon is a South Korean actress who is five years younger than Jang. She was born in 1997 and studied film at Konkuk University before beginning her acting career.
She made her screen debut in the 2019 KBS2 historical romantic drama The Tale of Nokdu, the same series in which Jang played the lead character, Jeon Nok-du.
That project became an important early connection between the two actors.
Their First Connection
Jang and Kim first crossed paths through The Tale of Nokdu in 2019.
Jang was already established in the drama’s leading role, while Kim was beginning her acting career. Their professional relationship continued beyond the television series, eventually bringing them together through another creative project.
Their relationship was not publicly confirmed during those years, allowing them to maintain a remarkably low profile.
A Private Romance
The couple reportedly spent a long period together without publicly discussing their relationship.
That privacy made Jang’s announcement particularly unexpected. Rather than revealing a highly public celebrity romance, he told fans that he would marry someone who had been beside him for a long time.
In his handwritten announcement, Jang explained that spending considerable time together allowed them to understand and care for each other more deeply. He described their decision as choosing to become each other’s closest support.
The tone of the announcement was noticeably personal rather than promotional.
From Actors To Partners
Their professional relationship developed further after The Tale of Nokdu.
Jang later moved behind the camera, taking on directing responsibilities. Kim became involved in projects connected to his filmmaking work, giving the pair another opportunity to collaborate creatively.
Kim starred in Jang’s feature film Nuruk, which was released in April 2026. Jang served as director, while Kim appeared as the leading actress. Their work together therefore evolved from co-stars into a director-and-performer partnership.
That shared creative experience became another significant chapter in their relationship.
The October Wedding
Jang and Kim will marry in October 2026.
According to BH Entertainment, the ceremony will be deliberately small and private. Rather than staging a large entertainment-industry wedding, the couple plans to hold a worship-style ceremony attended by their families.
No elaborate public guest list or large-scale celebration has been announced.
The decision fits the couple’s approach to their relationship, which has largely remained outside the celebrity spotlight.
His Handwritten Letter
Jang chose an intimate way to tell his fans.
On August 25, he posted a handwritten letter on social media rather than leaving the announcement entirely to his agency.
He acknowledged that deciding to marry involved considerable thought. He also explained that the couple had spent enough time together to see different sides of one another, building greater understanding and affection along the way.
Jang also thanked fans who had supported him throughout his acting career and asked them to view the unexpected news warmly.
Their Five-Year Age Gap
Jang was born in 1992, while Kim was born in 1997, giving the couple a five-year age difference.
The age gap has received some attention following their marriage announcement, although the more notable aspect of their story is the length of their relationship and the extent to which they kept it private.
Both are actors, but their careers have developed at different stages, with Jang becoming known for leading roles while Kim has continued building her screen career.
A Shared Creative Path
Their story is unusual because acting was not simply the setting in which they first met.
It became an ongoing part of their relationship.
They first appeared in the same drama, later worked together through Jang’s filmmaking projects and have now reached the point of becoming husband and wife.
Their professional connection has therefore stretched from television acting to feature-film production.
What Happens Next?
Jang is entering marriage while continuing his career as both an actor and filmmaker.
The October ceremony will mark the beginning of a new personal chapter, but neither he nor his agency has indicated that marriage will change his professional plans.
For fans, the biggest surprise may simply be how long the relationship remained outside public view.
After years of keeping their personal lives largely separate from their careers, Jang Dong-yoon and Kim Seung-yoon are now preparing to become a married couple.
Their journey began with The Tale of Nokdu in 2019, continued through years of private companionship and creative collaboration, and has now reached an October 2026 wedding planned around family rather than celebrity attention.
