Better if the rule is that they can collect in one person only then the story is focused on two mc's love progress. The rei and bother stuff is bad. I really hate that part. Or it's better if they are not brothers and make them side couple.
This is going to be echoing a lot of points that people have made, but whatever. I agree when people say a lot of things were unnecessary. Rei and the incest were totally not needed (and was disturbing). And the rape. There were multiple rape scenes. Honestly, the whole concept kinda reminded me of rape. The mage spreads pheromones that make other men touch them, sometimes without any consent. And I agree with a lot of people that Rei did get off too easy. He should be actually punished. I also wish the world was built a little more. The place where the cat and the hamster come from looks INCREDIBLE and I wish we could've seen that world a little more. Overall, I think the concept is interesting and the art is pretty cute, but if it just didn't have any rape and incest and was built a little more professionally, I actually think it would be a good manga.
