Our Unwritten Seoul tells the story of identical twin sisters Yoo Mi-ji and Yoo Mi-rae, both played by Park Bo-young. Though they share the same face, their lives couldn’t be more different.
Yoo Mi-ji was once a rising track star. But after an injury crushed her dreams, she drifted into a carefree lifestyle, taking odd jobs and living on the edge of society. On the flip side, Yoo Mi-rae is the picture of success—composed, smart, and working at a reputable public corporation. She’s everything society expects a “perfect daughter” to be.
One day, fate throws them an unexpected curveball that leads the sisters to switch lives. As they step into each other’s shoes, they discover long-buried family secrets, heal from past wounds, and learn what it truly means to live—not just for others, but for themselves.
