Dragon King's Bride
"My father knew that Sanjaya's daughter had feelings for me. He wanted to prevent Sanjaya from trying to switch the bride and replace you with Valencia if I were the one officially arranged to marry you."
Anna blinked in surprise.
"So, my father had to pretend to be some lecherous old man interested in a young girl. That way, you would remain the chosen bride."
He smiled faintly.
"Before he passed away, we had already planned to switch roles on the wedding day. He would become me, and I would become him."
"For us, a marriage in the human world isn't particularly important or legally binding."
"So, the marriage is only valid in your kingdom?"
"Yes, of course."
