Most K-dramas begin with two people falling in love. A Love Other Than Yours begins much later.
Seo Kang-joon and Ahn Eun-jin’s upcoming romance follows a couple who have already spent 10 years together. They have shared their happiest moments, difficult days, family problems, and all the boring little habits that come with knowing someone for a very long time.
Now, they are standing at a completely different kind of crossroads.
Marriage is supposed to be the obvious next step. But what happens when one person starts wondering whether the love they have always known is still the love they want?
That is what makes A Love Other Than Yours one of the more intriguing romance K-dramas coming this year.
Seo Kang-joon Is Not Playing the Typical K-Drama Boyfriend
Seo Kang-joon plays Nam Goong-ho, an assistant manager at Hunmin Confectionery who has been in a relationship with Lee Mi-do for 10 years.
Goong-ho is warm, sociable, and the kind of boyfriend who feels dependable rather than dramatic. He has been beside Mi-do through some of the hardest periods of her life, including her struggles with her career.
For him, their relationship feels like something solid. After 10 years together, marriage seems like the natural next step.
But that certainty begins to disappear when he senses that Mi-do's feelings are changing.
And that is where Seo Kang-joon's character becomes interesting.
Instead of playing the perfect rich heir or an emotionally unavailable chaebol, he is playing a man who has every reason to believe his relationship is safe, only to realise that love cannot always be secured by time alone.
Ahn Eun-jin’s Character Is Falling Out of Love With Her Own Life
Ahn Eun-jin plays Lee Mi-do, a film director who once looked like she was on her way to a successful career. Things do not go according to plan.
Her projects repeatedly fail, and she eventually reaches a point where the career she once dreamed about feels increasingly out of reach. Throughout all of this, Nam Goong-ho remains beside her.
But when Mi-do meets someone new, something unexpected happens.
She begins experiencing feelings she thought she had left behind.
That does not suddenly erase the 10 years she has spent with Goong-ho. Instead, it creates a much messier emotional conflict.
She has a stable relationship, someone who loves her, and a future she has already imagined.
So why does her heart suddenly feel different?
This Is What Makes the Romance Feel So Real
The most interesting thing about A Love Other Than Yours is that it does not treat long-term love as automatically perfect.
Ten years together can mean deep trust and comfort. But it can also mean routine.
You know exactly what the other person will order at a restaurant. You know how they react when they are angry. You have probably seen each other at your best and worst.
That kind of relationship can feel incredibly safe. But safety and excitement are not always the same thing. The drama seems interested in that uncomfortable grey area.
It asks whether people stay together because they are still deeply in love or because leaving someone after 10 years feels almost impossible.
And that is a much more complicated question than the usual K-drama love triangle.
The New People Who Shake Up a 10-Year Relationship
The story does not only focus on Seo Kang-joon and Ahn Eun-jin.
Lee Joo-ahn plays Han Tae-seung, a lawyer who becomes connected to Mi-do and unexpectedly changes the emotional balance of her life.
Jo Aram plays Park Su-ah, a younger colleague who enters Nam Goong-ho's world.
Neither character is simply there to create a predictable love triangle.
Their arrival forces both Mi-do and Goong-ho to look at their own relationship differently.
For the first time in years, they have to ask themselves whether their relationship is based on love, habit, loyalty, or simply the fear of starting again.
When and Where to Watch A Love Other Than Yours
A Love Other Than Yours will premiere on September 12, 2026, on KBS2 at 9:20 PM KST. The drama will have 14 episodes and will air on Saturday and Sunday.
International viewers will be able to watch the series on Amazon Prime Video, with the global release scheduled alongside its Korean broadcast. Prime Video has confirmed availability across more than 240 countries and territories.

Final Thoughts
Something is refreshing about a K-drama that does not pretend love becomes easier just because two people have been together for years.
Sometimes, knowing someone for 10 years can make you understand them better.
Sometimes, it can make you wonder whether you still know yourself.
A Love Other Than Yours looks ready to explore that uncomfortable space between loving someone, being used to someone, and wondering what life might look like with someone else.
And honestly, that may be what makes this one worth watching.
Would you stay with someone after 10 years if the relationship no longer felt the same, or would you choose to find out what your heart wants next?
