The highly anticipated Korean drama Our Unwritten Seoul officially hit screens today, May 24, 2025, with its premiere on tvN and global release on Netflix. Fans of heartfelt, character-driven stories now have a new weekend favorite, airing every Saturday and Sunday at 9:20 PM KST, taking the slot of Resident Playbook.

This fresh series introduces viewers to a pair of twin sisters whose decision to trade lives turns everything they thought they knew upside down. Park Bo-young takes on the challenging task of playing both Yoo Mi-ji and Yoo Mi-rae—two women raised together but living vastly different lives. Mi-ji is the free-spirited younger twin, once a promising track athlete before an injury forced her to rethink her dreams. Since then, she’s been picking up odd jobs, surviving on grit and hope.

Her older sister, Mi-rae, is everything she’s not—structured, responsible, and deeply rooted in her career as a government worker. Tired of the expectations and curious about each other’s world, the sisters swap places, setting off a chain of emotional and personal twists. Park Bo-young shines in this dual role, bringing out the subtle differences between each twin while also showing how pretending to be someone else forces them both to look inward. In a first for the actress, she even sports blonde hair to capture Mi-ji’s lively and rebellious vibe.

Joining the story is Park Jin-young.

Jin-young known for his work in K-dramas and as a member of GOT7. He plays Lee Ho-soo, a smooth and accomplished lawyer who appears confident but quietly struggles with insecurities that begin to unravel as the twins step into each other’s lives. Ryu Kyung-soo also features as Han Se-jin, a man who’s turned his back on corporate life and embraced a quieter path in the countryside. His calm, grounded energy offers a striking contrast to the tension building in the city.

The show was written by Lee Kang, best known for Youth of May, and directed by Park Shin-woo, whose past work includes It’s Okay to Not Be Okay. Together, they create a drama that doesn’t just rely on the twin-swap twist for drama but dives deep into what it means to be seen, to be stuck, and to grow in unexpected ways.
