🎬 Oxfea Review: Our Unwritten Seoul (2025)

What if your city forgot you—but your story still mattered?

Our Unwritten Seoul is not your average K-drama. Set in a dreamlike version of the capital, this 2025 gem paints a hauntingly beautiful portrait of Seoul as a city of memory, mystery, and missed connections. Told through intersecting lives—an aspiring writer, a grieving taxi driver, and a girl searching for her past—this series feels like a love letter to everything unspoken between us.

With poetic cinematography and a soundtrack that tugs at your soul, it’s slow-burning, deeply human, and quietly magical. Perfect for fans of My Mister or Move to Heaven, but with a surreal edge that’s all its own.

Oxfea says: Watch it when you’re craving something raw, thoughtful, and emotionally resonant. Seoul has never felt this personal.
