I DNF this book after 3 chapters, as the MC already has a full group of women in his life. They aren't a harem yet, though the first demon he runs into refers to them as the MC's harem. At least one of them has been a lover previously.
I don't like that kind of start to a series. I want to get to enjoy the MC meeting each LI, and see them find a path forward as a group. Those meetings were taken from us in this one, leaving a bad taste in my mouth. Combine that with the fact that the MC seems like he might be a bit of an idiot, and I decided to not invest more time into this one.
