What's A Villainess Supposed To Do Again?(2020)

Akuyaku Reijou tte Nani wo Sureba Iin dakke?

Cardinell regains memory of her past life, and she realizes she's been reincarnated from a romance-novel-reading 40-year-old lab researcher to a villainess in a romance game. The only problem is, she never actually played these games in her past life...

She just has a hazy idea of what will happen next, but Cardinell decides there's no point in fighting fate. She needs to suck it up, play the villainess, and get exiled!! What she can do is prepare herself for life after exile by learning more about medicine (her trade in her past life) and building strong bonds with her family. But, for some reason, the prince who she assumes is supposed to break off the engagement seems to actually like her... and the rest of the royal family, too...!!
