I have a question as well, even though the main game is an otome game, could we also change the format to a manga, anime, novel or webcomic if we don't want the story to take place in an otome game?
High school shoujo setting being less gruesome is the greatest idea ever! (Maybe instead of being killed, the villainess might either end up losing everything, arrested, or end up in a mental hospital).
But anyways, good luck on your other projects!
