The First Night With The Duke Plot
The drama centres on a contemporary college student (Seohyun) who is inexplicably drawn into the universe of a romantic novel. In this parallel universe, she wakes up in the body of a minor character named Cha Sun Chaek and finds herself in an unexpected circumstance: spending the night with Yi Beon, a strong and enigmatic duke who is the story’s obsessive male lead.
According to My Dramalist, as the heroine navigates palace politics, secrets, and her developing feelings for the male protagonist, she tries to change the novel’s original tragic ending. What starts as a perplexing and awkward turn of events quickly transforms into a deep and complicated love story.
The audience is left wondering what kind of surprising romance will emerge when the story’s notable male star meets a once-invisible supporting character. Standing near enough to sense the tension between them, Cha Sun Chaek and Yi Beon lock eyes in the gloomy nighttime light to start the scene.
