The Central Plot
Our Unwritten Seoul revolves around a pair of identical twin sisters—Yoo Mi-ji and Yoo Mi-rae—played by Park Bo-young in a powerful dual performance. Though they look exactly alike, their lives couldn’t be more different.
Mi-ji has spent her life in the countryside, quietly raising her grandmother and working odd jobs to get by. She once dreamed of becoming an Olympic track athlete, but an injury shattered that path. Meanwhile, Mi-rae thrives in Seoul’s fast-paced corporate world, working as a high-ranking executive at a fintech company. She’s composed, stylish, and everything her sister believes she’s not.
Their worlds collide when a sudden family crisis forces them to swap lives. What begins as a temporary plan quickly reveals long-hidden truths, unresolved family wounds, and the different choices that led them down separate paths. And as they settle into each other’s lives, they begin to rediscover their own.
Characters You’ll Remember
Yoo Mi-ji / Yoo Mi-rae – Played by Park Bo-young
This is a standout dual role where Bo-young brings depth and subtle differences to two characters who appear identical on the surface. Mi-ji is grounded, emotional, and introverted. Mi-rae is sharp, disciplined, and outwardly confident—but inside, she’s fragile.
Lee Ho-su – Played by Park Jin-young
Ho-su is a Seoul-based lawyer with connections to both sisters. He becomes the emotional bridge between the twins as he starts to unravel their story. Compassionate yet mysterious, Ho-su has his own secret motivations that are slowly revealed.
Han Se-jin – Played by Ryu Kyung-soo
Se-jin used to work in finance but now lives on the outskirts of Seoul running a small organic farm. He gets entangled with Mi-ji in unexpected ways and helps her navigate life in the city. His character symbolizes healing and simplicity in contrast to Seoul’s hectic lifestyle.
Kim Ok-hee – Played by Jang Young-nam
The estranged mother of the twins, whose reappearance in their lives triggers the beginning of their journey. She’s layered and complex—a mother trying to make amends while hiding her own regrets.
Yeom Beon-hong – Played by Kim Sun-young
A sharp-tongued but warm-hearted vice principal at Mi-ji’s old school and one of the few adults who supported her in her youth. She adds grounded humor and emotional insight throughout the series.
Why the Title “Our Unwritten Seoul” Matters
The word “unwritten” in the title refers to the untold stories, unexplored identities, and paths not taken. Seoul here is more than just a city—it’s a metaphor for complexity, anonymity, and possibility. As the twins trade places, they each uncover the parts of themselves that were hidden beneath societal expectations and personal doubts.
This drama doesn’t follow the typical “rich vs. poor” twin-swap trope. Instead, it uses the setup to explore how place and identity shape one another, and how the city of Seoul—like the sisters—holds layers of both pain and potential.
Themes That Resonate
Urban vs Rural Identity: The visual and emotional contrast between the sisters’ environments is stark. This drama beautifully captures the loneliness of Seoul and the warmth of rural life without romanticizing either.
Sisterhood and Memory: Their bond isn’t based on sweet flashbacks or childhood promises. It’s rooted in real pain, missed opportunities, and slowly rebuilding something that was broken for years.
Career and Burnout: Mi-rae’s story reflects the reality of corporate life in South Korea—achievement-driven, emotionally draining, and ultimately unsustainable if disconnected from purpose.
Redemption and Choice: As secrets unfold, each character faces a decision: cling to the past or rewrite the future.
What Sets This Drama Apart
Unlike fast-paced thrillers or melodramatic romances, Our Unwritten Seoul moves at a steady, reflective pace. It allows viewers to sit with each moment, with episodes often ending not in cliffhangers, but in quiet realizations. The cinematography uses Seoul as a silent character—its alleys, cafés, buses, and rooftop views all contributing to the emotional weight of the story.
And for K-drama lovers who enjoy OSTs, the original soundtrack features intimate acoustic ballads and piano instrumentals that elevate the mood without overpowering the scenes.

This drama shows that sometimes, the only way to truly move forward is to step back, revisit the past, and rewrite your place in the world.
