Yoo Mi-ji (Park Bo-young) and Yoo Mi-rae are identical twins who couldn’t be more different. Mi-ji is a former sprinter who gave up everything after an injury — now working odd jobs in her sleepy hometown of Duson-ri, caring for her grandmother with no plan for her future. Mi-rae took the opposite path: elite student, model employee, a perfectionist grinding through a high-pressure public corporation in Seoul. On the outside, she has it all together. On the inside, she is quietly drowning under workplace bullying she refuses to name.

When Mi-ji discovers what her sister is actually going through, she proposes something radical: swap places. For a few months, Mi-ji will become Mi-rae in Seoul — handling the office, the colleagues, the city. Mi-rae will step into Mi-ji’s unhurried countryside life. What neither sister expects is how much the other’s world will ask of them — and how much they’ll find in the asking. Into this swap walks Lee Ho-su (Park Jin-young), a lawyer with a tall presence and a carefully managed secret: he’s been partially deaf since a past incident, and has spent years working twice as hard to listen to a world he can only half-hear.

📺 Episode Guide

Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.

Our Unwritten Seoul Episode 1
EP 01
Mi-ji, Yet Unknown
May 24, 2025
Two sisters, one face, completely different lives — and the moment that sets them on a collision course. Lee Ho-su reappears in Mi-ji’s hometown after an absence, and the show wastes no time establishing the gap between who the twins appear to be and who they actually are. Park Bo-young differentiates the two in the opening episode with a subtlety that pays off for the entire run.

Our Unwritten Seoul Episode 2
EP 02
Review and Reassess
May 25, 2025
The swap begins — and immediately neither sister is as comfortable as she expected. Mi-ji finds Mi-rae’s corporate world dull until a difficult project forces her to actually try. Mi-rae, now farming, runs headfirst into Han Se-jin, who has no patience for a city girl pretending to know what she’s doing. The episode sets up the central irony: both twins are better suited for the life they didn’t choose.

Our Unwritten Seoul Episode 3
EP 03
Knock, Knock
May 31, 2025
Mi-ji digs into her Seoul assignment with full force — and Ho-su watches, a little surprised by her stubbornness. The episode does the important work of building the two lead relationships from scratch: Ho-su and Mi-ji’s dynamic starts here not as romance but as mutual recognition. Two people who are trying hard in ways no one around them fully sees.

Our Unwritten Seoul Episode 4
EP 04
What the Other One Carries
June 1, 2025
The first real cracks show. Mi-rae’s composure starts slipping in the countryside — she didn’t expect Mi-ji’s life to be this emotionally demanding. Mi-ji, meanwhile, begins uncovering just how much workplace toxicity her sister had been absorbing alone. The teenage flashbacks land well here; they reframe both sisters without making either one the tragedy of the story.

Our Unwritten Seoul Episode 5
EP 05
The Weight of Being Fine
June 7, 2025
Ho-su’s deafness becomes part of the conversation — not as a plot device, but as a quality that shapes how he moves through the world. Park Jin-young handles it quietly and without sentimentality. This is also the episode where rumours about Mi-rae (as Mi-ji) and Se-jin start circulating, and Ryu Kyung-soo shows exactly why Se-jin is worth watching: warm, unpredictable, real.

Our Unwritten Seoul Episode 6
EP 06
The Confession That Wasn’t
June 8, 2025
Mi-ji’s drunken confession reaches Ho-su — and neither of them knows how to process it inside a lie that’s getting harder to maintain. The episode is the midpoint and earns it: the web of identity is now tangled enough that the audience feels the pressure too. Kim Ro-sa’s thread with the restaurant storyline quietly deepens; Won Mi-kyung makes every scene count without ever demanding attention.

Our Unwritten Seoul Episode 7
EP 07
An Awkward Beginning
June 14, 2025
Mi-ji and Ho-su begin something — awkwardly, honestly, in the middle of a lie they haven’t yet confessed. The romance here doesn’t feel rushed because the groundwork was laid carefully. An unexpected appearance at work upends Mi-ji’s careful balance, and the episode ends on a note of genuine tenderness between two people who are, for the first time, not pretending to be okay.

Our Unwritten Seoul Episode 8
EP 08
Swap Back
June 15, 2025
The sisters return to their own lives — and neither fits anymore. Mi-rae goes back to her company and faces a confrontation with her past that she can’t sidestep this time. Mi-ji, briefly staying with Ho-su, navigates the strange intimacy of proximity without clarity. The episode is slower than the ones around it, but that slowness is the point: both women have been changed by living someone else’s story.

Our Unwritten Seoul Episode 9
EP 09
Mi-rae Fights Back
June 21, 2025
Mi-rae’s motivation reignites — and she decides to stop absorbing and start pushing back. The shift in Park Bo-young’s performance is precise: Mi-rae doesn’t become Mi-ji; she becomes a clearer version of herself. Meanwhile, Mi-ji and Ho-su uncover the truth about Kim Ro-sa, which reframes several earlier scenes and adds a layer of meaning to the countryside storyline that wasn’t fully visible before.

Our Unwritten Seoul Episode 10
EP 10
The Weight of Hearing
June 22, 2025
Ho-su’s health forces the question he’s been deferring: what does he actually want, beyond being functional? Park Jin-young carries the episode with an understated vulnerability that’s the best work he does in the series. Mi-rae takes a bold step toward the future — quietly, without announcement — and the drama earns the emotional weight it’s been building toward.

Our Unwritten Seoul Episode 11
EP 11
Facing the Past
June 28, 2025
Characters who have been living with emotional wounds finally stop managing them from a distance. The penultimate episode is the most emotionally demanding of the series — and the most rewarding. Every supporting thread, from Kim Ok-hui’s complicated motherhood to the Kim Ro-sa storyline, converges here with care rather than rush. The leads hold the weight of it without breaking.

Our Unwritten Seoul Episode 12
EP 12
The End Is a New Beginning
June 29, 2025
The finale doesn’t rush to tidy everything up — it gives each character the room to stand at a new beginning rather than a clean ending. Mi-ji enrolls in university, sets her sights on counseling psychology, and chooses the life she wants rather than the one she defaulted into. Mi-rae leaves her job and starts growing strawberries in the countryside — and makes it look less like a retreat and more like a choice. Se-jin returns from abroad. Ho-su embraces his hearing loss as part of who he is, not a problem to be solved. The ending is honest. That’s rarer than it sounds.

Our honest read on why this drama is worth your time — and who it’s for.

👯 Identity Swap Done Right

😭 Emotionally Honest
🏙️ Seoul as a Character

Park Bo-young has played sweet before — repeatedly, to great success. What makes Our Unwritten Seoul different is that she arrived specifically not to do that. As Mi-ji and Mi-rae, she’s playing two versions of exhaustion: one loud and directionless, one polished and quietly collapsing. The dual role works not because she swaps costumes and hairstyles — though those details are precise — but because she builds each twin from the inside out. The way Mi-rae holds her breath before she speaks. The way Mi-ji fills a room she’s already decided to leave. It’s the best performance she’s given since Daily Dose of Sunshine, and it carries more tonal range.

Our Unwritten Seoul (2025)

The drama has a pace that will divide viewers. Episodes run close to 80 minutes, and director Park Shin-woo — the same man behind Our Beloved Summer‘s lyrical quietness — lingers on countryside scenes, afternoon light, strawberry fields in the rain. If that sounds like filler, this isn’t the drama for you. If it sounds like the point, you’re in the right place. The romantic triangle is handled with more maturity than the genre usually allows: Ho-su’s partial deafness is written as character rather than tragedy, and Park Jin-young plays it with a stillness that makes the eventual emotional opening feel genuinely earned rather than scripted.

The middle episodes stretch, and some of the workplace-bullying plot lacks the specificity to sting the way the writers clearly intended. But the finale makes a choice that most healing dramas don’t: it gives both sisters an ending that looks like work, not rescue. Mi-ji enrolls in university. Mi-rae grows strawberries. Neither is handed a life — they choose one. In 2025, that’s the most romantic thing a K-drama could do.
