Final answer:
After the falling action in a short story, the denouement is the remaining part that needs to be written, providing resolution and closure to the narrative.
Step-by-step explanation:
After writing the falling action of your short story, the part you still need to write is the denouement. The falling action is where the tension from the climax starts to release, leading towards a resolution. Following the events of the falling action, the denouement, also known as the resolution or conclusion, is where the story's conflicts are resolved, and the narrative concludes, often leaving the reader with a sense of closure.
