Dear X Season 2 (2025) takes everything that made the first season so intriguing and deepens it, pushing the boundaries of suspense, romance, and mystery to new heights. Starring Kim Yoo-jung as Han Seo-ul and Kim Young-dae as Do Jun-se, the second season promises to deliver a rollercoaster of emotional tension, dangerous secrets, and heartbreaking choices.
The story picks up with Seo-ul, who had vowed to leave her infamous “Dear X” advice column behind after a tumultuous first season. Her writing once made waves, offering cryptic, almost prophetic letters to the troubled souls who sought her guidance. But when she starts receiving letters once again—this time predicting crimes in her signature style—her past quickly catches up with her. Seo-ul’s initial attempt to distance herself from the chaos of her own creations falls apart, as these new letters pull her back into the dangerous web of intrigue and personal turmoil.
Kim Yoo-jung’s portrayal of Seo-ul is at its most compelling here, as she is forced to confront both her own guilt and the painful memories of her past relationships. Her character, once determined to walk away from her past, is now thrust into a situation where the very thing she tried to escape is coming back to haunt her. The chemistry between Seo-ul and Do Jun-se, played by Kim Young-dae, is electric—charged with unresolved tension from their shared history and the choices that separate them now.
The standout mystery of Season 2 revolves around a copycat—someone who is sending letters in Seo-ul’s distinct style, but with a chilling twist. The copycat letters predict crimes that soon become a reality, pulling Seo-ul into a deadly game of cat and mouse. As the investigation deepens, Jun-se, now a prosecutor, recognizes the distinctive punctuation in the letters—the mark that only Seo-ul used in her columns. This revelation triggers an emotional and tense confrontation between them, as Seo-ul grapples with her involvement and the growing danger surrounding her.
The trailer is filled with haunting, atmospheric shots that set the tone for the series—rain-soaked streets lit by neon signs, shredded paper caught in the wind, and confessions made in secret locations like rooftops, each one adding layers of mystery to the already complex narrative. The tension between Seo-ul and Jun-se is palpable, as the two are pulled together and torn apart by the mysterious events surrounding the letters and the crimes they seem to predict.
One of the most compelling aspects of Dear X Season 2 is the slow-burn romantic tension. Seo-ul and Jun-se’s past relationship complicates everything, as trust is tested in ways that feel both personal and professional. Seo-ul is left to face a difficult decision: reveal her role in the case and expose herself to the man she once loved—or allow Jun-se to prosecute a woman he now suspects as the person he once knew. The emotional stakes are raised as their history intertwines with the dangerous present, making for a deeply compelling conflict that explores the complexity of love, loyalty, and guilt.
The film’s overall vibe is a slow-burn thriller, with text messages, letters, and cryptic clues creating an atmosphere of mounting suspense. The haunting piano-filled soundtrack, accompanied by the constant sound of rain on the streets of Seoul, heightens the feeling of isolation and urgency. As each episode unfolds, viewers are taken deeper into a labyrinth of lies, betrayal, and twisted fate, with the ultimate revelation hanging just out of reach. Every scene promises new twists and emotional gut-punches that will keep viewers hooked until the very end.
In conclusion, Dear X Season 2 promises to be an unmissable continuation of the romantic thriller that first captured the hearts of audiences. With its haunting atmosphere, emotional depth, and twists that keep you guessing, this season is poised to explore the complexities of love, crime, and redemption in a way that will leave audiences on the edge of their seats. The tension between Seo-ul and Jun-se, paired with the mysterious new letters predicting crimes, sets the stage for a season that will deliver both chills and heartache in equal measure.
