Plot: Our Unwritten Seoul
Yu Mi-Ji and Yu Mi-Rae (both played by Park Bo-Young) are identical twin sisters who couldn’t be more different. Mi-Ji, once a rising athlete, now lives on the margins—restless and without direction. Mi-Rae is everything Mi-Ji isn’t: polished, responsible, and respected at her government job.
After a moment of impulse—and growing dissatisfaction with their own lives—the two sisters decide to swap identities. What begins as a short lie quickly spirals into a transformative experience that neither could have predicted.
Caught in the middle is Lee Ho-Su (Jin Young), a lawyer with a dark past masked by a charming exterior. His unexpected encounters with both sisters unravel truths not just about them—but about himself, too.
In a city that often demands perfection, Our Unwritten Seoul asks: What if the most honest version of yourself is the one you’ve been hiding all along?
