Until the Exiled Duke's Daughter, Wilhelmina, Becomes Happy

Wilhelmina was born into the Periknen ducal family, one of the most powerful noble houses in the kingdom. Trained and educated to become queen, she was raised as the very embodiment of nobility. However, in order to justify the crown prince's infidelity, she was forced into marriage with a commoner.
Her husband, Alexi, however, turned out to be a man of exceptional intellect, conducting research capable of overturning the very foundations of the world's common sense. And as a man, once you looked past the surface, he was like an unpolished gem with the potential to shine brilliantly.
Little by little, Wilhelmina adjusted with an open mind to her new life among the commoners. At the same time, she began shaping Alexi both in body and spirit, setting her sights on exacting revenge against both the royal family that cast her aside and her own ducal household that abandoned her.
