Park Bo-young finds herself on the verge of a secret promise being uncovered.

In the 9th episode of tvN's weekend drama 'Our Unwritten Seoul' (written by Lee Gang, directed by Park Shin-woo and Nam Geon), which airs on the 21st, twin sisters Yu Mi-ji (Park Bo-young) and Yu Mi-rae (Park Bo-young) face a test due to the distrust and suspicion from their workplace superiors.

Previously, Park Sang-young (Nam Yoon-ho), who made Yu Mi-rae a public enemy, returned to work. After seeing Park Sang-young, who has the same face as her father, Yu Mi-ji, who is living a changed life with Yu Mi-rae, fell into a panic. Park Sang-young, mistaking Yu Mi-ji for Yu Mi-rae, intensified the confusion with the face of a kind superior. However, he soon revealed his true colors, conspiring with Choi Tae-gwan (Jung Seung-gil) and Shin Kyung-min (Lee Shi-hoon).

In particular, Park Sang-young felt a chill as he recalled Yu Mi-rae's twin after hearing Choi Tae-gwan and Shin Kyung-min say that Yu Mi-rae has been acting strangely. His keen intuition raised the possibility that Yu Mi-rae and Yu Mi-ji were living changed lives, and the next day, Choi Tae-gwan and Shin Kyung-min used the fact that even identical twins have different fingerprints. The two superiors urged Yu Mi-ji to open a door that operates with fingerprint recognition, and if the door did not open, the fact that Yu Mi-ji was acting as a substitute would be immediately revealed, leading to a tense situation.

As if to demonstrate the infinitely unfavorable situation facing the twin sisters, Choi Tae-gwan and Shin Kyung-min, as shown in the released photos, are pressuring her with expressions that alternate between suspicion and certainty. To make matters worse, the presence of Park Sang-young adds even more tension, amplifying the anxiety of viewers.

The public's interest is focused on whether Yu Mi-ji and Yu Mi-rae can safely navigate this crisis and deliver a powerful blow to their superiors, who are filled with disdain and pressure.

Viewers can meet Park Bo-young in crisis, caught in the schemes of her workplace superiors, in the 9th episode of tvN's weekend drama 'Our Unwritten Seoul,' airing at 9:20 p.m. on the 21st.
