Park Bo-young Confronts Her Inner Struggles in 'Unknown Seoul'

In the latest episode of tvN's weekend drama 'Unknown Seoul' (미지의 서울), which aired on June 21, 2025, Park Bo-young's character, twin sister Yu-mi-rae, begins to face her hidden emotional wounds after returning to her rightful place. The episode showcased a significant transformation for both Yu-mi-rae and her sister Yu-mi-ji, as they shed doubts and prepare to embrace new beginnings.

After completing a life-changing experience with Yu-mi-ji, Yu-mi-rae boldly proves her identity to her skeptical superiors. However, when colleague Kim Tae-i (홍성원) suggests they expose corruption within the company, Yu-mi-rae, still haunted by past traumas, declines the offer, trying to avoid reliving her previous pain.

Things take a turn when Kim Tae-i anonymously reveals the corruption on a company bulletin board, leading to renewed scrutiny and suspicion directed at Yu-mi-rae. Despite having done nothing wrong, she finds herself once again battling the ghosts of her past.

The pivotal moment comes when her former colleague, Kim Soo-yeon (박예영), a victim of workplace bullying, confronts her guilt for abandoning Yu-mi-rae during their struggles. This encounter allows Yu-mi-rae to unleash her pent-up frustration and anger, as she sees her own struggles reflected in Soo-yeon’s plight.

Empowered by this meeting and the support of Han Se-jin (류경수), Yu-mi-rae decides to take a stand against the perpetrator Park Sang-young, who has been shamelessly pretending to be a victim. Just as she prepares to take legal action against him, her sister Yu-mi-ji makes a dramatic entrance, delivering a powerful blow that leaves viewers exhilarated.

Meanwhile, Yu-mi-ji grapples with an unexpected identity crisis following her life change. Doubting her ability to achieve success under her own name, she receives heartfelt encouragement from her boyfriend Lee Ho-soo (박진영), which helps her regain confidence and resolve to carve out her own path.

A touching conversation between Yu-mi-ji and their mother, Kim Ok-hee (장영남), resonates deeply with viewers, as both women express their longing for each other's affection, leading to an emotional moment that highlights their unspoken bond.

As Yu-mi-ji and Yu-mi-rae gradually reclaim their identities, a new crisis looms for Rosa Restaurant owner Kim Rosa (원미경). Fearing exposure due to the corruption scandal, construction workers hasten the sale of the restaurant, while lawyer Lee Chung-gu (임철수) pressures Kim Rosa with threats of revealing hidden secrets, leaving viewers eager to discover what he holds.
