Our Unwritten Seoul

Flips the stereotype of identical twin closeness; healing family drama

Review

9.5/10 is my rating.

Our Unwritten Soul is a deeply emotional drama that blends romance, family struggles, and the complexities of identity with identical twin sisters at its center. The acting is phenomenal—especially from the actress playing both female leads, Mi-hi and Mi-rae. She captured each sister so convincingly that I never once lost track of who was who.

Mi-hi stood out as a character I really loved. She was kindhearted, thoughtful toward her family and friends, and always trying to support others even when she was hurting. Her warmth made it even harder to watch how her mother constantly criticized her and compared her unfavorably to Mi-rae.

The story tackles family expectations, sibling rivalry, and the ways love can both heal and complicate relationships. At times, it’s heavy and heartbreaking, but it’s never dull. Even the side characters—like the adopted mother whose fierce love for her son was one of the most touching parts of the drama—felt layered and real.

This is a romance at its core, but also a family-centered story that explores how we see ourselves and how others define us. It isn’t a light watch, but it’s beautifully done and meaningful. If you enjoy stories about complicated families, strong character growth, and romance that develops under unique circumstances, Our Unwritten Soul is worth your time.

Spoilers

Mi-rae, though compelling, often came across as selfish. She had Mi-hi take her place at work even though she knew it meant sending her into a hostile environment with bullies and even a sexual harassment situation. Mi-hi wasn’t warned and was told only to “sit quietly,” avoid the male lead, and keep secrets—while Mi-rae, when pretending to be her sister, behaved however she wanted. She ignored their grandmother at first, treated Mi-hi’s best friend who was her ex-boyfriend coldly, and worked the farm with little concern for how her choices would affect Mi-hi’s reputation. It felt unfair and very one-sided.

The relationship between the adopted mother and her son was another emotional highlight. Their eventual heart-to-heart about his guilt—believing he couldn’t call her his true mother—was powerful. I only wish he had told her sooner what he overheard his relatives saying about him being a burden. That moment could have added even more emotional depth.

Some story choices frustrated me. For example, Mi-hi keeping her secret from her romantic interest for so long felt unnecessary; he was proven trustworthy and capable of keeping confidences, so the delay only created avoidable frustration. The grandmother’s death also felt like an oddly placed plot point—it was heartbreaking, but it didn’t meaningfully move the story forward.

As for the ending, it leaned too “soft” for my taste. Mi-hi’s decision to go to school to become a therapist was wonderful, but the delay in marriage felt like it was playing into a modern “independence before romance” trend rather than being true to the heart of the story. A proposal or engagement would have been a more satisfying romantic payoff. Similarly, Mi-rae and “strawberry guy” had clear chemistry when he returned, but the lack of even a confession felt like a missed opportunity.

On the positive side, I appreciated how both sisters grew from the experience and came to understand themselves and each other better. By the end, their relationship was warmer and healthier, and it felt like the beginning of true healing from a mother who had always struggled to show love.

The two single mothers’ friendship—so different in background yet united in strength—was inspiring, and Rosa the poet’s arc was fascinating and uplifting in the end.

Overall, Our Unwritten Soul is a powerful drama with stellar performances and heartfelt themes. I recommend it highly, though it’s not a light or endlessly rewatchable story. It’s heavy at times, but if you stick with it, it rewards you with meaning, emotion, and a memorable exploration of love, family, and identity

It's like living a real life in a drama with very broken people.

I was reluctant to watch this drama for two reasons: The high rating here and the numerous average/below average reviews here (a very big contrast, i was like why?)

Anyhow, I gave in and i'm glad I did. As someone who loves romantic dramas, this drama gave me butterflies in my stomach.
I thought maybe they wrote this drama based on real people, and the story was not exactly a story but a narration of real people and real events. I felt like i lived with the cast while watching. I felt their pain, their sorrows, their longing. it was just beautiful.

Story:
Set in the countryside, the story revolves around identical twin girls and a boy named Ho-Su. They all had hard upbringings with heavy baggage in their adulthood. There are lots of trauma-related and depression issues introduced too. The characters are all broken, which made this drama very realistic. Romance is not the major plot of this story but the development of the twins and their love lives is beautifully depicted.

Writing:
I initially thought this is based on real-life people or a novel, but whoever wrote this drama interestingly made it appealing and heartfelt. unless one is so lucky in life to have an easy life, we all suffer in different areas, and sometimes it's soothing to see how healing happens in a world full of chaos. The only issue with the writing was miscommunication. albeit minor, this could have been developed better.

OST:
As a sucker for bgm tracks in Korean dramas, this one had a marvelous choice of OSTs. The songs are all beautiful and memorable. The pieces sometimes gave me goosebumps as they matched the mood perfectly.

Acting:
PBY never disappoints. i haven't been a fan of hers and only watched a few of her dramas, but delivering the twins' characters and emotions was hard, and she did amazing.
PJY, well, he delivered a green forest guy who smiled with his eyes. I loved how gentle and kind his character was and he wasn't afraid to show his vulnerability. Kudos to both!

Romance is very important to me and this drama's romance was more like a subplot, but it felt like it was there from the beginning. The first-love trope existed from the first episode and the adult Miji-Hosu's relationship and chemistry was amazingly beautiful. wish they had more initmate/kiss scenes though lol.

Overall, a beautiful drama. i'm glad the negative reviews and the super high rating didn't sway me.

So much better than expected!!!

I loved this drama!!!! I love how it portrays difficult family dynamics and how the certain behaviour of people comes from deep pain, sorrow, grief, or trauma.
In general I love how things got resolved in the end, not in a fairytale, unrealistic way but it showed how you have to put in some effort in order to succeed. Things won’t change for the better just because you want to.

I want to go through each character that I liked or had certain thoughts of:

1. The twins Miji and Mirae:
I definitely liked Miji more and also could relate to her much more. She was bubbly, energetic and loud. She took care of her grandma and did all kinds of jobs and her dark past made me sad and I could also relate to her a bit.
Tbh Mirae seemed like a very pale character next to Miji, almost boring. Throughout the majority of the drama I really disliked her. When the harrassment happened at work, I tried to feel sorry for her but I was annoyed again!!! like WHYYYY did she suggest to forget about what he tried to do???? Idk but that was soooo strange and kinda unrealistic!!! as a woman, if my colleague starts to harrass me I would cancel every contact with that person, even consider leaving the company!!!! And she just wanted to move on like nothing happened??? I got SO mad at her!!!! The only thing I liked about Mirae was her relationship with Han Sejin, the strawberry farmer 😂

Which brings me to the next character!

2. Han Sejin aka the strawberry farmer:
I loved this guy!!! I already saw him in Lovestruck in the City where he plays an author and I already liked him a lot in that drama! He was actually one of my favorites 😂 And hos character in this drama was amazing too!!! Definitely one of my faves!!!

3. Lee Hosu:
I know he is the Male Lead but somehow I liked the Second Male Lead much more, again 😂 Le Hosu was just ok. I felt sorry for him at some parts especially when he was younger. I didn’t like how he treated his mom, so there were some scenes when I got really annoyed with him because I really liked his mom! She was my favorite character! So I was happy when I watched the scene when his mom comes to Seoul and hits him and then they hug and cry and I cried so much in that scene too!!!! 😭😭😭

which brings me to my next character:

4. Bon - Hong aka Hosu’a mom:
I LOVED this woman so much!!!! Everything she said and did was so touching and sweet and I loved her fighting with Ok-hui 😂😂😂 idk if I am biased or not because she is a Reply 1988 actress but I genuinely loved Bonhong so much!!! Her quotes were my favorite 😂

5. Ok-hui aka the twins’ mom:
At the beginning and throughout the whole drama I was SO annoyed with her!! Her talking aggressively ALL THE TIME put me so much on edge!!!! She is mean to everyone literally! To Bon-hong, Miji, her mother, just everyone!!! I got so fed up with her until the scene she cried on the floor with the real Miji and then cried at the hospital in her mother’s lap. Her story was maybe one of the most heartbreaking and although I still dislike her aggressive side, I got to like her in the end…

7. Kim Rosa aka Sangwol:
Her story was one of the most impressive! I cried so much! The way she protected her friend gave me goosebumps!!! When women love and help each other they can move mountains!!! Her story was such a story! I was so happy she got a happy end so quickly! 🥰 It was so heartwarming!

8. Tae-i and his sister:
I cant really say much about his sister, but I really loved Tae-i!!! As a very minor character he was very well done! I would have liked to see more of him!

9. The grandma:
Once again, a drama with a grandma plot can never disappoint!!! One of my favorite Korean words is the one for Grandma, (halmeoni) because some of my favoritr dramas are the ones that have a kind grandma starting (e.g. Start-up).

I would say this is it for the main characters!
I just love this drama and lowkey want a season 2 just to see Mirae get together with Sejin. Also I feel like the twins are both the main characters but it felt more focused on Miji. So I wonder whether there shouldn’t be a part 2 which focuses more on Mirae 😍

Yin and Yang

This show is brilliant. I love how this show just hurts and heals. It was both painful yet heartwarming.

This is the story of two sisters. A story of a culture that expects too much yet gives too little.

Park Bo-young is an amazing actress. No question about this. She played the part of twins like there were actually 2 actresses. You can tell which is which. She acts with such restraint and force, it just works. She's definitely one of my favorite K-actresses. I would watch anything she's in!

This series is 12-episodes short/long, it is engaging and the story is character-driven. The pacing of the story is seamless and does not drag.

If you want a story about empathy, healing, identity, family, and some intergenerational trauma mixed in, this is for you.

Our Unwritten Seoul: Healing, Frustration, Repeat

At first, I was hesitant about whether or not I should start this drama, but in a moment of boredom I just went for it. To my surprise, the plot turned out really interesting. I liked the concept of twins switching lives, which is tricky to pull off, but Park Bo Young did a great job.

🌸 POSITIVE ASPECTS:
-The acting during sad scenes was so good (I actually teared up more than once). It had a very great impact.

-The character development of the mother was slow but satisfying, which makes it realistic in my opinion.

-I liked how they encouraged taking a break when you're feeling hopeless and tired. Healing and self-care are more important than a job and that’s on period.

Overall the plot and execution was nice, not flawless but nice.

⚡ NEGATIVE ASPECTS:
-This is more of a personal statement rather than a critique. I just couldn’t get on board with Mirae’s character. I know she had suffered workplace bullying and was most likely depressed, which led her to attempt, but I just couldn’t understand why she stayed that long just to suffer. Also, she was very cold and strict at first so it just wasn’t for me, but I still respect the execution and her character development.

-Some aspects of the story felt unexplored and made me raise questions, like Lawyer Lee’s behavior. I still don’t know why he was so ruthless at first and then just randomly became better.

-Honestly i didn't feel chemistry between the main leads and just wasn't that interested in their love story.
Also, and I can’t stress this enough, I HATEEE the miscommunication trope and the “I’m a burden for you let’s break up” trope. It literally made me rage because the main leads were grown ass people who had already experienced something similar in high school and couldn’t even learn and move forward as fast as I wish they would have.

Overall these are the main aspects that ruined some of the drama, plus a few boring scenes here and there but nothing too major.


Our Unwritten Seoul tries to teach us to prioritize our health, both physical and mental, and that it’s never too late to start over and be who you wanna be.

This is a story of two girls born as identical twins. The story begins at birth and continues into their thirties. Though they are identical twins, this is where the similarly stops. Both are very different characters who have had many different experiences in life. As the series proceeds, each of the girls, Mi Rae and Mi Ji, learn about each other's strengths, weaknesses, and misconceptions of each other. Misconceptions being key, as this seems to happen to all the characters in the series. From their mothers and fathers, to past classmates, business associates and friends. These misconceptions and miscommunications are what the characters must work out and move forward in their lives.

I believe this is the first series review where I can point out how excellent the production team did on creating this series. I remember in many past shows where the same actor/actress were performing two different characters in the same camera shot. These were incredibly done in this series. Best I have ever seen. So seamless that it is hard to believe it is the same actress doing both parts. Well done. A++++

There was not too much in-depth drama in this series. But the cast and crew performed outstandingly. It was a show I feel that made the viewer feel happy, hopeful, and supportive of all the characters in the series. Sometimes you just need a loving and feelgood show to watch. And this was it.

As usual, all the actor's/actress's performances were great. I did not note any outstanding soundtracks to add to my playlist.

I would recommend this series, and look forward to seeing these same actors/actress again in future projects.

I rate this series an 8 out of 10.

I love this drama because of the story. So many of life lessons presented here. Individual struggle, siblings pov, family relationship, childhood & adulthood problems and more. Not only the lead casts, but also the support actors are amazing and have their own stories that made them reasonable to act like the way they did. I was drawn into their acting that I cried a few times.
I don't remember anything about the soundtrack, but the story is stuck in my head.
This drama is perfect for those who lost in life that might need a little push to do what you believe is true.

Very good drama

This was really good but those expecting a lot of romance would be disappointed. For me this is more of a slice of life than a romance.

All actors were awesome too. I already like the FL actress but she did so well here especially playing twins. I can really tell the difference between the two.

ML was good too IMO. His acting befits his character and I liked that he isn't the typical ML who is either dour and a bit of a a*hole or an eccentric one who's also a bit of an a*hole (lol). I liked he seems like an actual human being, a bit introverted but understandable given his life.

I also liked that all my questions about the story were answered at the end (maybe one that is not so clear). A bit too much cutesy stuff at the end but that's quite common with kdramas so that's ok.

Also Bun Hong is my bias. She's such a sweetheart and she maid me cry in one of the episodes. She wasn't even acting with overtly drama, just simple delivery but vuta through the bone.
