I Stole the Male Lead's First Night

Due to a mistake one night, I became the target of the most obsessive man and a villainess! After possessing Ripley, a count’s daughter and an extra in a novel, I became the female lead. Since this is the case, I will try to enjoy the riches and luxuries of a nobleman that I couldn’t experience in my past life. I can remember up to drinking alone in a corner at a party… but I woke up the next day in the male lead’s bed!
