Writer-chan, I hope you don't make a harem in Black Clover novel because first it's really disgusting (sorry for those who like this type of novel but I don't like it) secondly with Madara's character it's impossible for him to do that and also even if he changes his pride and pride won't allow him to so I hope that You just keep on Yuno as the beginning of the novel because they are very nice and it wouldn't be nice to change husbands in the middle of the novel and Madara won't change his feelings easily and in vain because if he resolves on something he will do no matter what happens so I hope you continue on Yuno or Harem even though that is your choice in the end
Sorry if it bothered you
