A Notorious Villainess Enjoying a Life of [Talentless and Incompetence] in Her Third Life

Once upon a time, there was a princess notorious for being the epitome of incompetence and evil. Driven mad by jealousy after her fiancé was stolen from her, the princess attempted to summon a demon, using the lady who stole him as a sacrifice. However, at that moment, the crown prince, who was her half-brother, rose up and defeated both the demon and the princess.
“Hehe, truth is stranger than fiction.”
—But that’s fine.
As the princess, I was truly healed in another lifetime.
Yet, being reborn in the same world and becoming a duke’s daughter, she found herself once again scorned as an incompetent and useless figure.
Nevertheless, the duke’s daughter, Labianje Robur, continues to wear a graceful smile and lets the ridicule slide off her like water off a duck’s back.
“Because being deemed incompetent and useless has its perks, doesn’t it?”
