You can start by making a list of strong, vivid words related to your story. Let's say your short story is a mystery set in an old mansion. Words like 'haunted', 'secrets', 'corridors' could be on your list. Then combine these words in different ways to form titles. 'Secrets of the Haunted Corridors' or 'The Corridors of Hidden Secrets'. Also, think about using metaphors or symbols from your story. If there's a character who is always looking out of a window, 'The Window to Another World' could be a creative title.
Look at the main theme or emotion of your story. For example, if it's about loneliness, a title like 'Alone in the Shadows' could work. Or focus on a key object in the story, like if there's a special ring, 'The Ring of Destiny' might be good.
