أنمي Yowaki MAX Reijou Nano ni, Ratsuwan Konyakusha-sama no Kake ni Notte Shimatta

I was reborn as a villainous daughter in a reverse harem otome game.

After being sick with a high fever at the age of 10, Pia Rockwell suddenly remembered her past life as a university student in Japan. But far from going down the villainess route, all this super timid girl wants is to finally use her knowledge from when she was a grad student studying to get her doctorate in paleontology. Her ultimate goal is to become a commoner, excavate fossils, build a museum and then become a curator.

So in order to escape the villainess route and avoid being deported by her fiancé during the graduation ball, Pia decides to avoid the upcoming hurt and heartache and asks to break off her engagement to Rufus, the Prime Minister's son.

But will her cunning fiancé let her go that easily?
