This is something I really hate and it's usually when I do angst prompts. If the ending is sad and you don't like it, don't say "I'll just cut the ending off" because it pisses me off. The prompt is something you want to imagine as a whole. Do not cut the ending or the sad part out. You can just NOT imagine it.
