Watashi wa Kaibutsu Ouji no Hisho

As if it weren't enough to be born as the bastard child of a noble, Valenti meets her final demise by starving to death after being sold as a slave by her very own father in her bankrupt country. But when she wakes up again, time has been rewound to right before she was sold as a slave. From then on, Valenti vows to become the lady in waiting to the so-called monster prince, to escape her horrendous past life's fate, and to hold up the prince as the nation's true emperor for her beloved country. After graduating summa cum laude as a lady in training, she chooses not to accept the prized fate of becoming an attendant to the empress, but to the one individual nobody would want to support. But her plans become mixed up when her position as lady in waiting is challenged by... love?! (Source: POCKET COMICS)
