I loved the part at the beginning about "I'm Her Favorite Character (in a Reverse World)," especially when his sisters and mother appeared. Could you please do a story about yandere incest in a reverse world? I'm sure if you write it, it will be a masterpiece.
I would have preferred something with a harem, like more sisters or maybe the mother like "I'm Her Favorite Character (in a Reverse World)," . Even so, I am sure that it will be an excellent novel since you are the one who writes it.
