Our Unwritten Seoul (Korean: 미지의 서울) is a 2025 South Korean television drama series set to premiere on tvN and stream globally on Netflix.
Starring Park Bo-young, Park Jin-young, and Ryu Kyung-soo, the emotional series tells the story of twin sisters with opposite personalities who swap lives and embark on a transformative journey through deception, family tension, and self-discovery.
Airing twice weekly beginning May 24, 2025, this weekend drama blends heartfelt emotion with secrets, romance, and the vibrance of Seoul life. The themes of identity, truth, and family make it compelling, but its mature tone warrants caution for younger viewers.
Our Unwritten Seoul Age Rating
Our Unwritten Seoul is rated TV-MA for mature thematic elements, emotionally intense scenes, and adult subject matter. This rating suggests the series is intended for adult audiences and may not be suitable for those under 17. Here’s a closer look at the key content areas:
Violence
Violence is minimal and mostly emotional or psychological. There may be confrontations, arguments, or depictions of mental distress, but physical violence is rare or implied. Some scenes involve tense family dynamics and personal trauma that may be emotionally heavy for sensitive viewers.
Language
The Korean dialogue includes occasional strong language, though not excessively. Subtitled translations may include emotionally charged expressions or mild profanity in moments of anger or distress.
Sexual Content
The series includes romantic subplots and some intimate moments between adults. These are generally implied or shown tastefully, with occasional passionate kissing. Nudity is not expected, but emotional intimacy and relationship complications are key parts of the narrative.
Mature Themes
The central plot revolves around deception, identity, abandonment, and the psychological consequences of living a lie.
Themes like familial rejection, emotional neglect, lost love, and mental health struggles are explored throughout the show.
Characters also deal with trauma, broken relationships, and self-worth — topics that require emotional maturity to fully process.
Is Our Unwritten Seoul Suitable for Teens?
Ages 10–12: Not suitable. The thematic complexity and emotionally intense storytelling are inappropriate for pre-teens. The tone is somber, and topics such as identity loss, family dysfunction, and personal trauma are too advanced for younger viewers.
Ages 13–17: Use caution. While there is little graphic content, the mature emotional themes may be difficult for younger teens to grasp. Older teens who enjoy serious dramas or are fans of the actors may be interested, but parental guidance is advised, especially for discussions around mental health, deception, and complex relationships.
Our Unwritten Seoul is best suited for viewers 17 and older who can appreciate its emotional depth and morally complex storytelling. It is not designed for casual teen viewing or light-hearted entertainment.
What Parents Can Do
Preview Episodes: Watch the first few episodes to understand the tone and complexity of the narrative before allowing teens to watch.
Talk About Identity and Deception: If teens are allowed to view the show, use it as a springboard for conversations about honesty, emotional growth, and personal choices.
Provide Context: Some cultural nuances, family expectations, and relationship dynamics in the show may benefit from explanation, especially for non-Korean audiences.
