I was forced to have a Marriage Contract with The Serpent Queen (GL)!

Contract Marriage. Two lands have made, the kingdom of the serpent queen, ruling over demons and the other was a human kingdom close to ruin. The King has offended the ruler of the neighboring country, to plead mercy he decides to barter his daughter as a gift. "To the Serpent Queen, I give you my daughter. Promise me you won't do anymore harm to my lands and people, frail and sickly she may be but she can do any favor you may ask of her." The King bit his lip feeling guilty and horrible for his choices. He has talked to his daughter beforehand of her faith, for the people she loved to grant safety she decided to agree with the prospects of marriage with a being she hasn't met. "You bring me your daughter? An offering worthy for a demon such as I, a princess to devour-" The Serpent Queen using her human form, walked on her legs and came forward to meet the princess that has been offered. A beauty- to envy. "Greetings to her highness." The princess opened her eyes and saw that she wasn't afraid. Intrigued she saw her eyes were different, cloudy and of milky color. A blind princess, something easy to manipulate and surely she's spoiled. "I am in a bind, I am thankful the king is gracious with such a gift. I was looking for a wife." She held the girl's chin, eyeing the beauty carefully and thought she'll do just nicely. "A... Wife?" The princess tilted her head innocently, the Serpent Queen nods and kisses the girl sweetly, her tongue slithering in and the father averted his eyes feeling angry. "Marry me, human or your whole kingdom will suffer under my thumb." The princess agreed, but soon she never realized she would have the Serpent Queen under her thumb instead. Wife to Wife, a love story after marriage.
