love an ending that is 'happy' in that a desirable outcome is produced, but made complicated by the fact that the protagonist has given up something integral to themself in order to make it so. it's sort of uncool in some circles to admit you LIKE when characters give up something really cool for something pretty basic, but it's all about context and quality of storytelling, right? that sort of conviction - this is a part of my personality that i am permanently renouncing access to, and it's my choice, and i'm going to miss it, but i'm not going to regret it - that's compelling. ending in which a character who loves nothing more than the rush of finding the answer to a question is handed, one day, a puzzle they just don't want to solve. and that part of their life is over, but it's not a bad thing. maybe the answer doesn't need to be known. maybe not knowing it opens you up to a creative mindset you never had before. character who gains some kind of special power chooses to give it up not because they no longer love the ability, not because it hasn't improved their life, but because this thing they love comes with costs, is getting in the way of a life someone they love or loved and lost would want them to live. i'm glad it turned out this way. i miss the missing thing with all my heart. i would let go of it again if i was asked to choose.
