Well, another term could be 'heartbreaking story'. A sad story often makes you feel sorrow, and a heartbreaking story has the same effect. It can break your heart when you hear about the misfortunes, losses or difficult situations in the story.
A 'doleful story' can also be used instead of a sad story. The word 'doleful' has a connotation of sadness and grief. It makes you think of something that is mournful or depressing. For example, a story about a character who has lost everything - their family, their home, and their hope - can be described as a doleful story.
Account. For example, when someone is giving a description of an event that happened, it can be seen as an account, which is also a form of story. It may be more factual than a fictional story, but still a sequence of events told in a certain way.
Well, another term could be 'the denouement'. It's that part of the story where all the loose ends are tied up, secrets are revealed, and the final outcome of the plot is shown. For example, in a detective story, the denouement would be when the detective finally reveals who the killer is and how the crime was committed.
