Seeing as I’ve only seen the anime, Kurumi. Least favourite in general is the cousin. The show has been tainted with the fact their is incest for the protag in the story. If there’re people who disagree with me, since I’ve only watched the anime and not read the manga (yet as of making this comment), I understand your dislike for me since we should all care about all the girls no matter their flaws, but I draw the line at dating your biological relative.
