After she helped her younger sister defeat the tyrant, her younger sister became the king and she became a Duke.

There’s only one thing to do now – to help her younger sister keep her oath to God, and to be able to do that, she first had to get married.

“I know what oath you made to God. Please marry me for three years, just three years. Then after that, I will divorce you right away.”

The illegitimate son of the tyrant, the prince, has proposed a contractual marriage.

“I will never love you because you don’t want love. I will just be your perfect, impeccable husband.”

What is he saying?
