i reincarnated as a villainess, so what?! (unedited and on hiatus)

on her birthday Catherine recalled the memories of her past life thanks to being hit by a door. the next day she'd learned that she was reincarnated as the villainess of a manga she once read, destined to have a destruction end. catherine thought 'what to do?' then suddenly an idea came up she will become a cupid villain, she will bully the heroine and make all villains in the world cry in shame on her greatness! she will help the heroine to have a happy ending with the male protagonist while she slowly laid her safety nets to ensure that her family and her will not fall into ruin. what a perfect plan!!!
