   These are all some of my favorite Undertale stories. The first one is one I wrote myself, currently at over 60,000 words, which is a bit short… But don't be fooled by the title!! It's definitely not an otome game! And it doesn't involve female rivalry! This is clearly a satirical and satirical book against those ridiculously written and bizarre all-female otome stories! 😢
