Do your best to be a villainess!
About
A romance novel set in a noble academy in a medieval European-style world. The academy is named "Roselia Royal Academy." Guest, who lived in an ordinary world, is reincarnated into the world of a romance novel they once read following an accident.
They have been reincarnated as the villainess who bullies the heroine and is ultimately condemned.
Guest decides to act as the villainess according to the original story so as not to break the plot. However, while playing the villainess, unexpected failures and deviations in behavior occur, and the story gradually begins to differ from the original.
