In the Our Unwritten Seoul episode 1, started airing on the 24th and has already drawn attention with its emotional depth and complex characters. In the first episode, viewers met identical twins Yu Mi-ji and Yu Mi-rae, both played by Park Bo-young. They looked and sounded exactly alike, but they led completely different lives. Mi-rae worked in Seoul at a government-run company. Mi-ji, once a talented track athlete, gave up her dreams after a serious injury and now works as a school janitor.
The drama opens with tension. The sisters haven’t spoken in over a year. Though close during childhood, something caused their bond to break. Their mother, Kim Ok-hee (played by Jang Young-nam), lives with Mi-ji but favors Mi-rae. One harsh conversation shows how deep the resentment goes. Ok-hee criticizes Mi-ji’s lifestyle, pushing her emotionally. Mi-ji tries to defend herself, but it ends with her walking out after saying she would rather die than burden her sister.
Not long after, Mi-ji runs into her childhood friend and first love, Lee Ho-soo (played by Park Jin-young). Their reunion isn’t warm. Ho-soo keeps asking about Mi-rae, which upsets Mi-ji. But after they talk more, he shares that Mi-rae has been acting strangely. She’s avoiding people and seems to be in a fragile mental state. He reminds Mi-ji how close they used to be and asks her not to give up on her sister.
Eventually, Mi-ji visits Mi-rae at a cafe. Their talk is tense. Mi-rae makes a dark comment about how it’s better to fall from the third floor than suffer quietly. Mi-ji tries to reason with her, but it’s clear Mi-rae is struggling. The next day, Mi-rae doesn’t go to work. Instead, she climbs onto a ledge at home. Mi-ji returns just in time to grab her hand, and both of them fall together.
Luckily, they land on a mattress that Mi-rae had placed earlier. Neither is seriously hurt. But what follows is a raw, emotional moment between them. Mi-rae lashes out, angry that Mi-ji interfered. Mi-ji responds tearfully, asking how she could ever let go of her sister. For the first time in a long while, the two hug and cry. It’s clear the pain runs deep, but so does the love.
A Painful Past and a Bold Decision
Later, it’s revealed that Mi-rae had been mistreated at her job. She was targeted by a senior colleague and endured unfair treatment for nearly a year. The constant stress pushed her to the edge. Mi-rae admits she wasn’t trying to get back at anyone. She just felt empty. She didn’t want to face another day of work. Mi-ji listens, heartbroken.
When Mi-rae tries again to harm herself near the Han River, Mi-ji stops her. She links their fingers, quietly promising to take her place. Mi-ji says she’ll live Mi-rae’s life and take on her burdens, so Mi-rae can rest. She asks her sister to live her life instead. They agree to switch lives.
This moment feels like a turning point. Mi-ji stepping into Mi-rae’s shoes isn’t just an act of love. It’s her way of helping her sister heal, even if it means putting her own life on pause.
In the preview for the next episode, Mi-ji is seen working at Mi-rae’s company. She’s trying to fit into a world she doesn’t know. Viewers are now curious to see how long she can keep up the act and what changes might come from this big switch.
The first episode of Our Unwritten Seoul tackles real and heavy issues—family pressure, mental health, career struggles, and sibling rivalry. But it handles these themes with care. The story feels grounded. Nothing is overdone or exaggerated. Park Bo-young plays both roles with subtlety, making each twin feel like a separate person even though they look identical.
This show doesn’t rely on big twists. Instead, it focuses on emotions, relationships, and the quiet things people carry inside. Viewers who enjoy slow, character-driven dramas will likely connect with it.
By using twin identity not just as a plot point, but as a way to explore deeper emotional wounds, Our Unwritten Seoul offers something fresh. It’s not just about switching lives. It’s about learning how to forgive, rebuild, and truly see one another.
Whether Mi-ji and Mi-rae can keep up the life swap remains to be seen. But one thing is clear—they’re finally starting to understand each other, not as perfect mirrors, but as two different people who both need healing.
