Seo Kang Jun and Ahn Eun Jin Preview 10-Year Romance in ‘A Love Other Than Yours’

Seo Kang Jun and Ahn Eun Jin are setting the stage for a romance shaped less by a sudden spark than by the difficult questions that arrive after years together. KBS2’s upcoming series A Love Other Than Yours follows a couple entering their tenth year of dating, when the comfort they have built begins to collide with changing expectations about love, commitment, and the future.

The drama is scheduled to premiere on September 12 at 9:20 p.m. KST. A newly released look at its first script reading introduces the central relationship and the characters whose presence may unsettle it. Rather than framing a long relationship as a finished destination, the series places its leads at a crossroads: should familiarity lead toward marriage, or does it reveal that the relationship has reached its natural end?

A relationship tested by time

Seo Kang Jun plays Namgoong Ho, an assistant manager on a snack-company task-force team. He is described as warm and upbeat, with a life that has long revolved around his girlfriend. The role asks him to balance the ease of a partner who knows someone deeply with the quieter uncertainty that emerges when love and trust no longer feel identical.

Ahn Eun Jin takes on Lee Mi Do, a film director confronting the practical pressures that accompany adulthood and career setbacks. Her character’s emotional conflict is tied to the gap between the life she imagined and the reality in front of her. That tension gives the drama a grounded starting point: even a stable couple can be changed by work, family, and the individual ambitions each person is still trying to protect.

The script-reading material emphasizes the pair’s lived-in chemistry. Namgoong Ho and Lee Mi Do are not strangers learning one another’s habits; they are people who have already seen one another at their best and worst. Their shared history is expected to be central to the show’s emotional texture, allowing small shifts in tone or routine to carry as much weight as a larger confrontation.

New pressures around an old bond

The story also builds tension through the people entering each lead’s orbit. Lee Joo Ahn portrays Han Tae Seung, a lawyer at Lee Mi Do’s film production company. His professional conflict with her begins when he delivers difficult news about her job, while a growing personal interest adds another layer to an already strained situation.

On Namgoong Ho’s side, Jo Aram plays Park Soo Ah, a junior colleague who appears unexpectedly in his workplace. Her reserved first impression contrasts with a warmer side that becomes clearer over time. The character gives the drama another opportunity to explore how long-standing relationships can be affected not only by betrayal or spectacle, but by the attention and possibility that arrive during an unsettled period.

Workplace life is therefore more than a backdrop. Namgoong Ho’s office team and Lee Mi Do’s production-company environment bring daily stress into the couple’s private world. The series appears interested in the way career identity, professional disappointment, and office relationships can quietly reshape conversations at home.

Family and workplace add dimension

A wider supporting cast will place the couple’s dilemma within family and community. Kim Mi Kyung plays Lee Mi Do’s mother, Ma Sook Hee, while Kim Nam Hee and Lee Min Jae appear as her older and younger brothers. Their scenes are expected to bring family warmth as well as another perspective on the choices Lee Mi Do faces.

Lee Joon Hyuk plays Um Ho Sik, Namgoong Ho’s boss, adding a senior figure to the office storyline. Together, the family members and colleagues make the drama’s world feel broader than its romantic triangle-like pressures. They also underline the premise that a major relationship decision rarely belongs to just two people; it is felt through work schedules, family expectations, and the people who have watched the couple grow together.

A Love Other Than Yours arrives with a premise that favors emotional observation over easy answers. Its central question is not simply whether a couple will stay together. It is whether two people who know each other intimately can still make a deliberate choice to move forward when the early intensity of love has changed shape. With Seo Kang Jun and Ahn Eun Jin leading the cast, the drama will explore that answer when it premieres in September.
