dont know why ppl read a harem series and complain about the possibility of a heroine entering the MCs harem, probably the same dudes that complain about NTR in a NTR themed story, or about the amount of violence in a gore and violent story.
Well, I'm not worried for any of them. It's either A. Lilith grew strong enough to prevent Shirley dying, or B. Weiss saves the day for everyone yet again
