A nice repreive from what I predict is a volume or two full of suffering.
After rereading the previous chapter, I really am starting to dislike the cousin. You were a witch, a supernatural existence just like the mc, to whom you pledge your "love", yet you never trusted her with this info. Would've probably eased her isolation a lot, to know there are other "non-humans" like her.
But nah, keep her as a useful insurance you do. Selfish kind of love, B rather than a W you are.
