About Secret Door
Ham Jae-kyeong, a successful adult web novel writer, suddenly finds herself in a slump. She rewrites her writing and characters keep overlapping. Se-hee, the CEO of a web novel company, is Jae-kyeong’s friend. Se-hee suggests to Jae-kyeong that she write a SM novel as a way to overcome her slump. At first, she refuses, but after being persuaded by her assistant writer, Gi-dong, she meets Seong-soo, who enjoys SM play. Jae-kyeong is drawn to the handsome and well-mannered Seong-soo. Is he researching for her novel or is he in a relationship? Growing increasingly captivated by Seong-soo’s charm, she begins to embrace SM play.
Directed by Lee Dong-hyun, Secret Door leans on a strong ensemble — Oh Ji-yoon, Jang Tae-gyeom, Kim Dan-ah — to carry a story that balances spectacle with character.
The film landed with audiences for its craft and performances, and remains one of the most talked-about romance titles of 2025.
