Think about the main theme or the most interesting aspect of your story. Use that as a starting point for the title. It could be a key emotion, a unique character trait, or a surprising event.
A good way to title short stories is to consider the ending. If it has a powerful or unexpected conclusion, hint at it in the title. Like 'The Unexpected Twist' or 'The Last Revelation'. Another approach is to use a metaphor or a symbol that represents the core of your story.
You can try to make the title short and catchy. Something that grabs the reader's attention immediately. Also, using vivid words or creating a sense of mystery can work well. For example, 'The Secret of the Old Mansion' or 'Fading Hopes'.
