Wilhelmina was born into the Duke of Periknen, one of the most senior aristocrats in the kingdom. She was given a high level of education in order to become queen, and was raised as an aristocrat among aristocrats, but she was forced to marry a commoner in order to justify the infidelity of her fiance, the crown prince. However, her husband Alexi was a brilliant mind, conducting research that overturned common sense, and as a man, he was like a diamond that could shine if polished. Wilhelmina was flexible and gradually adapted to the life of a commoner, while training Alexi's body and mind, and set out to take revenge on both the royal family and the duke family that unjustly banished her from aristocratic society!
