The Case She Married Into - Episode 4

A couple's car stops on a narrow road, so they walk into a remote village and find a dead crow hung to ward off spirits. Locals greet them as royalty, calling the husband "Your Highness" and explaining a New Year ceremony where he will play the Crown Prince and she is expected to be the Crown Princess. The welcome flips when a villager accuses her of bringing a "dark aura" and shouts, "She must be executed!" The episode ends on that demand, the welcome silenced and her fate left hanging.
