I was reborn as a villainess after being a dried-fish woman, but there are so many villainess stories that I don't know which one I was reborn into.

"Critia, as of today, I'm breaking off our engagement! Don't interfere with Mira and me!" Rena Kurita, a dried-up woman whose only schedule is drinking alone at home every night, suddenly finds herself reincarnated as a villainess in some story. She's suddenly told her engagement is broken off, but Rena, who doesn't play games, read novels, or manga, has no idea where she's been reincarnated to. With no way to prepare, what action does Rena take?
