To be honest, I thought she was imagining her cat as a schoolgirl at first, which is even weirder to me than just having some random schoolgirl in her apartment.
@LordFifthIsLife That's more people screaming about the girl apparently not being the most pure thing in the world. Only having been kept in a dark corner until she allowed out at age 20 for marriage is all they will allow. People did the same thing with Meguro with that manga until her backstory was finally TL'd and then those same people did a complete 180.
