I definitely haven't seen a female protagonist like Bertria...she wholeheartedly from the time she remembered she had a past life just started spouted it out...since she's suppose to be a villainess that ruins Price Cecil's love life with the fated maiden that becam her soul objective because somehow it would lead to a happy ending for the prince. Even though being betrothed as children was more so for political reasons...her blunt honesty and unpredictableness is quite funny and cute through it does get her into trouble if her family, servants, and fiancé weren't looking out for her. I liked seeing how easily things come to the genius Prince Cecil, but being a natural at things can be quite boring and dull...it's cool that Bertria's knowledge of how the "plot" and characters are supposed to be mixed in with her determination actually brings spice to the Prince's life. Also, I liked that Bertria decided to save her mom even if it meant her dad not becoming evil, and somehow she saved one another one of her main leads by having an open communication with him. Oh an I love how spirits are essential beings in using magic! Plus it's always nice seeing the main lead(s) fall for the would-be-villainess who turns out to be more interesting than the heroine!
