I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This is weird. The main character, Danna, keeps sliding into monstrous visions she calls her "hospital nightmares." The husband, Danna's new employer, seems like he could be an escapee from Night Vale, the wife is possibly extremely unwell, and I have a feeling the two servants mainly stick around because their employers are compensating them extremely well (not just limited to paychecks, but top-of-the-line cell phones, money sent to relatives in need, etc.). It's difficult to imagine anyone raising a child in that house, because it's decorated in nightmares - every painting and sculpture is deeply disturbing in some way.
Oh, and there's a random capybara named Princess.
