This is amazing! I really like the main character's self-awareness, and how stuck on normalcy she is - it makes her pretty oblivious to outrageous events conspiring.
I'm betting it's a cross between the Duke's Daughter and the Middle Aged Man's Noble Reincarnation, because she's determined to be a Villainess! But her comments always fall slightly short. Or maybe it's going to be a comedy like the oblivious Bakarina? I like how happy she is to be fulfilling...
