>>279703903 (OP)Since the vast majority of these stories do not attempt to be a replica of reality, rewarding the hero with a cute girl serves to add an inspiring ideal to the story. "If you do good things you might be rewarded" is plain, but still uplifting, and I prefer that over a severely dumbed down approach to stoicism or, even worse, salaryman cuckoldry. There is a time and a place for each type of story.
