Plot Overview:
Our Unwritten Seoul follows the lives of identical twin sisters, Yoo Mi-ji and Yoo Mi-rae, portrayed by Park Bo-young. Mi-ji, once a promising athlete, now leads a carefree life, taking on various odd jobs in her hometown. In contrast, Mi-rae is a perfectionist working in a high-pressure corporate environment in Seoul. Despite their close bond in childhood, the sisters have grown apart over the years.
When Mi-ji discovers that Mi-rae is struggling with severe burnout and depression, she proposes they switch lives, just as they did when they were children.
