Is it just me, or do I sense the implication that the 'villainess' is also a reincarnator, and basically just decided to poke at the massive plot hole a harem ending represented in the original otome game and snag the secret character for herself instead of playing by the guide?
Also, I always find it hilarious when reincarnators like this 'heroine' are surprised by the fact that no, things don't work like they do in the game.
