Seo Kang Jun and Ahn Eun Jin Trace a Decade of Love in ‘A Love Other Than Yours’ Teaser

Seo Kang Jun and Ahn Eun Jin are set to explore the quieter, more complicated side of romance in KBS 2TV’s upcoming series A Love Other Than Yours. The drama has released its first teaser, introducing a relationship that has lasted long enough to feel inseparable—yet has begun to change in ways neither partner expected.

The series follows Namgoong Ho and Lee Mi Do, a couple entering their 10th year together. What began as a childhood friendship gradually became a romance shaped by years of shared memories, routines, ambitions and affection. The teaser frames that history as the emotional starting point for a story about what happens when a familiar love no longer feels entirely predictable.

From childhood friends to longtime partners

The preview moves through different stages of Namgoong Ho and Lee Mi Do’s lives, beginning with their early days as children. It then revisits their school years before arriving at their adult relationship. The quick progression gives the couple’s connection a sense of depth: their bond is not built on a sudden encounter, but on a long record of growing up alongside one another.

That shared past gives the drama’s premise a particular tension. A relationship with so much history can offer comfort and certainty, but it can also make emotional shifts more difficult to name. A Love Other Than Yours places its focus on those subtle changes, rather than treating romance as something that reaches its conclusion once two people become a couple.

Seo Kang Jun plays Namgoong Ho, whose affection for Mi Do is tied closely to the person she has always wanted to become. A key moment in the teaser shows him watching her at a film set as she pursues her dream of becoming a director. His perspective suggests a romance rooted not only in their past, but in his admiration for her drive and her future.

A romance about change after familiarity

Ahn Eun Jin’s Lee Mi Do looks back on the intensity of the couple’s earlier days, recalling a time when their world seemed centered on one another. The contrast between that memory and the drama’s present-day premise signals the question at the heart of the series: how do two people respond when the feelings they thought they understood begin to take a different shape?

The teaser does not position change as a simple sign of an ending. Instead, it presents it as an unexpected emotional turn in a relationship that has already endured through multiple chapters of life. That approach gives the drama room to examine devotion, disappointment, personal ambition and the challenge of seeing a longtime partner anew.

The pairing also brings together two actors familiar with character-driven storytelling. Seo Kang Jun has often balanced restraint with emotional vulnerability in his screen roles, while Ahn Eun Jin has established a strong presence across projects that move between warmth, humor and more serious dramatic stakes. Their collaboration will be central to making the couple’s long history feel believable within the series’ contemporary setting.

September premiere ahead

A Love Other Than Yours is scheduled to premiere on September 12 at 9:20 p.m. KST. With its first teaser, the series has established an intimate scale and a clear emotional question: whether a love that has changed can still become a source of renewed understanding. For Namgoong Ho and Lee Mi Do, the next stage of their relationship may ask them to look beyond the story they have already shared.
