Everything We Know About Dear X (2025) – A Dark Tale of Love, Betrayal, and Survival

K-drama fans are in for a gripping ride this year with the upcoming thriller melodrama Dear X (친애하는 X). Combining elements of noir, crime, and romance, the series promises a complex story of love, manipulation, and revenge—all wrapped in a glossy showbiz setting.


Plot Overview

Baek A Jin (Kim You Jung) grew up in a violent household, enduring years of domestic abuse. To survive, she developed an uncanny ability to read people’s hearts and manipulate their emotions. Outwardly generous and kind, she hides a ruthless streak that surfaces when angered or when it serves her purposes.

Now a top actress with beauty, fame, and talent, Baek A Jin’s public persona hides her darker nature. The only person she has ever fully trusted is Yun Jun Seo (Kim Young Dae), a childhood companion who has stood by her side all her life. But in a shocking twist, Jun Seo—driven by motives of his own—sets out to orchestrate her downfall.

Another constant in her life is Kim Jae O (Kim Do Hoon), a man who also suffered abuse growing up and found solace in his connection with A Jin. She became his reason to live, creating a deep, if complicated, bond between them. Meanwhile, Im Re Na (Lee Yeol Eum), a top actress and former idol, harbors feelings for Jun Seo, adding more tension to the tangled web of relationships.
