First Impression: Think The Devil Wears Prada meets a Thai GL slow-burn romance. Episode 1 of Gap does exactly what a pilot should: it introduces the central conflict, establishes clear personalities, and leaves you wanting more.
The Past (1996): The episode opens in the city of Iltan, where a terrifying serial killer named "Gap-dong" is terrorizing the community. He targets women and leaves a distinctive mark at his crime scenes. A brash detective, Yang Cheol-gon, leads the investigation. Under immense pressure to solve the case, Cheol-gon coerces a mentally challenged young man into confessing to the crimes, hoping to close the case quickly. However, during the process, the young man dies in custody. The detective is disgraced, but the murders suddenly stop, leading the town to believe the killer has vanished—or that the wrong man was accused.
The Present (18 Years Later): Detective Yang Cheol-gon is now a fallen officer working a menial job, obsessed with the idea that the real Gap-dong is still out there. Meanwhile, in the same town, Han Do-hoon—the son of the man falsely accused and driven to suicide all those years ago—is living a quiet life. He works as a webtoon artist and harbors a deep resentment toward the police. gap dong ep 1 eng sub
The tension reignites when a copycat murder occurs. A woman is killed using the exact signature of Gap-dong from 18 years ago. Cheol-gon rushes to the scene, convinced the original killer has returned. The episode concludes with a chilling cliffhanger suggesting that the legend of Gap-dong has not died, and a new game of cat-and-mouse is about to begin.

Some viewers find Gap Dong too bleak or convoluted in later episodes. But Episode 1 alone is a masterclass in:
We meet Sam (Freen Sarocha), a cold, perfectionist boss who inherited her grandmother's company. She's demanding, rarely smiles, and commands every room she enters. Then there's Mon (Becky Armstrong), a bright-eyed new employee who has idolized Sam for years—ever since she saw her speak at a university event. We meet Sam (Freen Sarocha), a cold, perfectionist
The episode quickly sets up the power imbalance: Mon is assigned to Sam's team, and her first day is a trial by fire. Sam is dismissive, sharp-tongued, and seems to take a particular interest in making Mon's life difficult. But Mon isn't easily scared. She pushes back in small, respectful ways, catching Sam off guard.
