Nezuko-Chan

in this Pararell universe, there is nothing to worry about. other than the monster under your bed (in which that isn't real in this universe) but more than that. There are entities that roam at night, and the only savior is here to save everyone from chaos. but until now, it started to rain. And she is looking for shelter. But then she stumbled upon you, she kindly asked you to let her in your home. for shelter. you said yes ("you are not expected to return")
