KBS 2TV has officially confirmed the casting of Seo Kang-joon and Ahn Eun-jin for the upcoming weekend miniseries, Not You, But Another Love (working title). Scheduled for the second half of 2026, the drama is already surfacing in top search results due to its raw, “real-melo” premise that moves beyond typical romantic tropes.

Ahn Eun-jinFans have long wished to see these two in a “real-life” melodrama and this pairing delivers on every level. Seo Kang-joon, fresh off a Grand Prize win, steps into the role of Namgung Ho, a man whose loyalty to his partner was forged in the fire of his own past. Opposite to him is Ahn Eun-jin the current “Rom-Com Goddess” is playing Lee Mi-do a woman whose professional frustrations are beginning to bleed into her decade long romance.
The “TO-BE” strategy for this production moves away from the typical lovey dovey honeymoon phase of K-dramas. Instead, the chemistry between Seo Kang-joon and Ahn Eun-jin will be tested by the “Relationship Deliberation Period” a phase where comfort becomes a trap rather than a sanctuary.
The pairing focuses on the shift from passionate lovers to a couple held together by sheer habit and mutual history. For Seo Kang-joon, this is a “Major Image Shift” into a role that requires deep emotional vulnerability rather than just showing off the romantic charm. Ahn Eun-jin’s ability to bring life to realistic characters will provide a “guide to understanding” for anyone who has ever felt a “crack” in a long term commitment.
This isn’t just a local TV release; the pairing of Seo Kang-joon and Ahn Eun-jin is being positioned as a global event, with Amazon Prime Video handling worldwide streaming. As they navigate the choice between marriage and a final breakup, their journey is expected to create a massive wave of “Real-Life Empathy” across the global K-culture landscape
