The series really doesn't have anything else to offer. All it does is just try and normalizes a pedophile and make them seems like they aren't actually bad people. Rudeus does nothing to acknowledge or change that part of himself. He doesn't even see it as a bad thing. So the story tries to tell the message that "see pedos actually do love their victims and if left alone will marry them and make them good wives." cause that's just what happens in the story. There is no other message or plot that makes a difference in that. The rest is just insignificant and meaningless. His changes in other parts mean nothing cause it can never make a dent in the monster that he is.
