Prime Video has set a date for its next Korean romance, and the premise stings a little. A Love Other Than Yours premieres September 12 in more than 240 countries and territories. Seo Kangjun and Ahn Eun-jin play a couple who have been together for ten years. Marriage looks like the obvious next step. Then one of them starts looking somewhere else.
A Love Other Than Yours Starts Where Most Romances End
Most romance dramas end at the confession. This one opens long after it. Namgung Ho and Lee Mi-do have already survived the messy years together, so their passion has cooled into something quieter. Both of them call that trust. But comfort and love are not always the same thing, and the show knows it.
Ho works as an assistant manager at Hunmin Snacks. He wins a room over in minutes, and he believes marriage is simply what comes next. Mi-do directs films, and her career has stalled badly. During that slump she meets someone new. Her feelings surprise her, because she has spent a decade certain about Ho.
That is the fragile line the series keeps pressing on. After ten years, is choosing each other still love? Or has it quietly become habit? Prime Video asked it that bluntly in the show’s own press release. So it clearly sits at the heart of the story.
The Cast
Seo Kangjun leads as Namgung Ho. Fans know him from Undercover High School and Cheese in the Trap. His character has leaned on Mi-do through every hard turn in his life. He assumes their bond can take anything. Then it cannot.
Ahn Eun-jin plays Lee Mi-do, once a promising rookie director. She comes to it from Dynamite Kiss and Hospital Playlist. Fans praise her for making romance feel real rather than staged. Here her work has stalled and her spark is gone. Then she falls for a man she did not even like at first.

Two Newcomers Shake the Balance
Lee Joo Ahn plays Han Tae-seung, an ambitious attorney at Jaekang Law Firm. He grew up an orphan with only his smarts to lean on. So he built a career as the managing partner’s loyal lapdog. Lately he has started questioning that life. Then he meets Mi-do, who keeps catching him off guard.
Jo Aram plays Park Su-a, an employee at Hunmin Snacks and the daughter of a famous soccer player. People call her cold. She just does not do warm, so she shows people only what they need to see. Jo Aram sang with K-pop group Gugudan before she moved into acting.
Neither newcomer is just a love triangle prop. Instead, each one shows up what the main couple has been missing. That is the harder version of this story, and it is the one the trailers keep selling.

The Team Behind It All
Hwang Seung-ki directs alongside Lee Garam. Hwang made The Matchmakers and Radio Romance, so he has spent years on romance with a comic edge. Yoo Su-Ji writes the series after Somehow 18. Together they are working in a KBS weekend slot that expects real numbers.
The team calls the show a real-world romance about feelings most long-term couples know well. According to Soompi, the team wants viewers to sit with the comfort of a decade-long couple while small emotional shifts creep in.
Should they move forward with marriage, or finally choose a love other than each other’s?
That line comes straight from the official release, and it is doing a lot of work. Notice that the show does not promise a reunion. It promises a decision.
Why This K-Drama Could Hit Hard
Korean romance has spent years perfecting the meet-cute. Lately, though, these shows have drifted toward messier ground. Stories about doubt and slow drift now pull real crowds. A Love Other Than Yours lands right in the middle of that shift.
The casting helps a lot. Ahn Eun-jin is one of the surest hands on Korean TV when a scene has to hurt. Seo Kangjun brings an easy warmth that makes Ho’s certainty ring true. So when that certainty cracks, the fall should be worth watching.
Then there is the small matter of how close to home it hits. Almost anyone in a long relationship has wondered if staying is a choice or just a habit. Very few dramas ask that out loud. This one looks ready to.
How to Watch A Love Other Than Yours
Korean viewers get the series on KBS2 every Saturday and Sunday at 9:20 p.m. KST, where it takes over the slot most recently held by The Husband. Everyone else streams it on Prime Video, and the global rollout runs alongside the Korean broadcast. Members can also download episodes and watch offline at no extra cost.
The show lands during a busy stretch for Prime Video’s Korean lineup. It joins titles such as Head Over Heels and Surely Tomorrow in the catalogue. For a fuller picture of the production timeline, casting reports trace the project back to early 2026. It also spent months under a different working title, as Dramabeans noted when KBS locked in its fall lineup.
Fourteen episodes is a tight run for this kind of story. That is probably a good thing. A slow burn can turn into plain stalling, and a short run pushes these two toward an answer. Whether the answer pleases anyone is another question. The September 12 premiere will start to tell us.
