The new drama airs every Saturday and Sunday at 9:20 PM KST on tvN.

“Our Unwritten Seoul” is a romantic coming-of-age drama centered around twin sisters who are identical in appearance but polar opposites in personality. One day, through a twist of fate, they end up switching lives – a decision that forces them to navigate unfamiliar roles, rediscover themselves, and reexamine what truly matters in life and love.

The show explores the emotional landscapes of these two women as they step into each other's worlds: one, a bright and energetic soul struggling in the countryside; the other, a reserved and overworked office worker living in the heart of Seoul. Through the swap, each begins to confront the emotional wounds they’ve long buried, sparking healing and transformation.

One of the most talked-about aspects of the series is lead actress Park Bo-young’s ambitious performance – she plays not just two, but four personas. As twin sisters Yoo Mirae and Yoo Miji, and as each pretends to be the other, Park Bo-young brings stunning nuance to every interaction. Her ability to shift seamlessly between restrained, emotionally guarded Mirae and bright, expressive Miji – and then portray each one impersonating the other – is nothing short of masterful.

K-drama fans already know Park Bo-young for her roles in “Strong Woman Do Bong-soon” and “Doom at Your Service”, but “Our Unwritten Seoul” is arguably her most demanding role yet. Fans and critics alike are praising her for her depth, precision, and emotional resonance, with many calling her performance “career-defining”.

Also starring in “Our Unwritten Seoul” is actor and GOT7 member Park Jin-young, who plays Lee Hosu, a brilliant and emotionally complex lawyer. At first glance, Hosu is all about logic and control, but his path crosses with one of the twins – revealing layers of vulnerability, past wounds, and unresolved affection.

Park Jin-young’s acting as Hosu is calm but very moving. With just a look or a pause, he shows the deep emotions of a man who keeps his feelings inside but still longs for connection. Whether he's arguing in a serious scene or quietly thinking about his past, Jin-young adds emotional depth to the drama’s main themes of love, regret, and healing.
