Park Bo-young Stars in 'Unknown Seoul' as Twin Sisters

In a bold narrative twist, Park Bo-young takes on a dual role as twin sisters in the newly premiered tvN weekend drama 'Unknown Seoul' (미지의 서울), which aired its first episode on May 24, 2025. The plot centers around Yu Mi-ji and Yu Mi-rae, who, exhausted by their respective lives, decide to swap their identities. The sisters share a secret promise, stating, "I will live as you, and you will live as me," which heightens the drama's intensity.

Yu Mi-ji, having left her career as a track athlete, now lives in the rural village of Du-son-ri, caring for her grandmother and engaging in local community work. In contrast, her older sister Yu Mi-rae appears to lead a successful life working for a public corporation in Seoul, but she is actually struggling with workplace bullying and isolation. After receiving a cold response from her sister during a phone call, Yu Mi-rae attempts a drastic decision, leading Yu Mi-ji to also find herself in a precarious situation.

In a heartfelt moment reminiscent of their childhood, Yu Mi-ji proposes that they switch lives, setting the stage for a unique story that only twins could experience.

The premiere episode achieved impressive ratings, with an average of 4.2% in the metropolitan area and a peak of 5.5%, making it the top-rated cable and general programming show during its time slot. Park Bo-young's performance, seamlessly transitioning between the vibrant Yu Mi-ji and the emotionally scarred Yu Mi-rae, has garnered positive reviews from viewers.

With the warm storytelling of writer Lee Kang and the artistic direction of director Park Shin-woo, 'Unknown Seoul' effectively contrasts the urban landscape of Seoul with the serene countryside of Du-son-ri, creating a rich visual experience. The second episode is set to air on May 25 at 9:20 PM.
