What happens when life gets too heavy to carry alone? If you’re Yoo Mi Ji and Yoo Mi Rae, twins played by the ever-charming Park Bo Young, you switch lives. Yep. You literally become each other. That’s exactly what the brand-new teaser of Our Unwritten Seoul teases, and we’re already hooked.
A Glimpse Into Seoul’s Unwritten Story

The teaser opens with Park Bo Young’s new drama giving us a heartfelt monologue: “We were together from the first page of our lives.” It immediately sets the tone, this isn’t just about twin sisters. It’s about a shared history, quiet suffering, and a desperate need to start over.
Yoo Mi Rae is drowning in city life, think endless noise, emotional burnout, and the kind of exhaustion you can’t nap away. On the flip side, Yoo Mi Ji is rooted in calm countryside living, but not without her own struggles.
“Let’s Switch.” And Everything Changes.

One of the teaser’s biggest punches? The moment Mi Ji says, “Let’s switch.” No dramatic music. Just a quiet offer that changes everything.
From there, scenes flash: Mi Rae awkwardly settling into village routines, Mi Ji navigating Seoul like a lost puppy, and both of them trying not to lose themselves in each other’s shoes. You can feel the tension, will this actually help them heal, or just break them further?
Jinyoung and Ryu Kyung Soo Bring Emotional Backup

Enter the male leads.
Jinyoung as Lee Ho Su is all soft eyes and solid support. He tells Mi Ji (pretending to be Mi Rae), “I will help you,” and honestly, same. We’d help her too.
Then there’s Ryu Kyung Soo as Han Se Jin, a former hedge fund manager turned countryside sage (only in K-dramas, right?). His line, “You see better in the dark,” feels like a poetic slap to the soul.
They’re not just love interests, they’re emotional anchors in this identity storm.
The Teaser’s Final Line Leaves Us Breathless
The closing scene of the teaser? It hits hard.
“The teaser ends as Yoo Mi Rae and Yoo Mi Ji resolve to make a brave attempt to take on life once more.”
No loud music. Just quiet determination and teary eyes. And just like that, we’re all in.
