Hey, everyone! How’s it going? Today I’m here to review the drama Our Unwritten Seoul, which follows identical twin sisters who decide to swap lives when their individual paths become too overwhelming. This Korean series showcases Park Bo-young’s incredible range as she portrays both twins, delivering a touching story about identity, family, and finding yourself.
Our Unwritten Seoul premiered on May 24, 2025, and concluded on June 29, 2025, airing every Saturday and Sunday at 21:20 (KST) on tvN. The series is available for streaming on Netflix and consists of 12 episodes with an average duration of 60 minutes. Written by Park Shin Woo and featuring an ensemble cast including Park Bo-young, Park Jin-young, and Ryu Kyung-soo, this drama combines romance, family dynamics, and personal growth.
The series explores themes of identity, self-acceptance, and the grass-is-greener mentality through the lens of twin sisters who couldn’t be more different despite sharing the same face. Set against the backdrop of Seoul and rural Duson-ri, the story presents a fresh take on body-swap comedies with emotional depth and character development.
Plot Overview: When Sisters Switch Lives
Yoo Mi-ji and Yoo Mi-rae are identical twins with completely opposite personalities and lifestyles. Mi-ji was a promising sprinter who quit sports due to an injury and now lives a free-spirited life in her hometown of Duson-ri, taking care of her grandmother without a concrete plan for her future. Mi-rae has always been a model student and perfectionist who currently works at a government-owned company, following an elite path since her school days.
When both sisters face personal struggles and feel trapped in their respective lives, they make an audacious decision to swap identities. This exchange forces them to confront their own assumptions about happiness, success, and what it means to live authentically. The series explores how walking in someone else’s shoes can lead to unexpected self-discovery and appreciation for one’s own journey.
Yoo Mi-ji: The Free Spirit Finding Direction
Park Bo-young portrays Mi-ji, the younger twin who ended her promising athletic career due to injury and now embraces a carefree lifestyle in the countryside. Mi-ji’s character represents those who feel lost after their dreams are derailed, struggling to find new purpose and direction. Her journey through the identity swap reveals hidden strengths and helps her realize that freedom doesn’t mean lack of responsibility.
Bo-young’s performance captures Mi-ji’s vulnerability beneath her seemingly carefree exterior, showing how someone can appear confident while actually feeling directionless. The character’s growth throughout the series demonstrates that sometimes we need to step outside our comfort zone to rediscover our true potential.
Yoo Mi-rae: The Perfectionist Seeking Authenticity
Mi-rae, also played by Park Bo-young, embodies the pressure of perfectionism and societal expectations. As the older twin who has always followed the conventional path to success, she represents those who achieve everything they’re supposed to want but still feel unfulfilled. Her experience living as Mi-ji teaches her about spontaneity, joy, and the importance of authentic relationships.
Park Bo-young’s dual performance showcases her remarkable acting range, creating two distinct characters who feel like completely different people despite sharing the same face. Mi-rae’s journey from rigid perfectionist to someone who learns to embrace imperfection resonates with viewers who feel trapped by expectations.
Lee Ho-su: The Lawyer Caught Between Two Worlds
Park Jin-young plays Lee Ho-su, a lawyer working for a large law firm who becomes romantically involved with both twins during their identity swap. His character serves as both a romantic interest and a mirror for the twins’ personal growth, as he must navigate his feelings while the sisters discover who they truly are.
Ho-su’s relationships with both Mi-ji and Mi-rae highlight the series’ themes about authenticity in relationships and how we present different versions of ourselves to different people. His character development adds depth to the romantic subplot while supporting the overall narrative about self-discovery.
Supporting Characters: Family and Community
The supporting cast, including Kim Sun-young and Jang Young-nam, creates a rich tapestry of family dynamics and community relationships. The grandmother figure provides wisdom and stability, while workplace colleagues and friends in both Seoul and Duson-ri represent different lifestyle choices and values.
These characters help illustrate how our environment shapes us and how changing our surroundings can lead to personal transformation. The contrast between urban Seoul and rural Duson-ri becomes almost a character itself, representing different approaches to life and success.
