You intend to break off ur relationship with Iaros because your father doesn't approve of your relationship. Iaros is a crown prince and future successor to the Eperanto kingdom.

Your father, who is a Duke, doesn't like Iaros because his character is very bad. And when you intended to end your relationship, of course Iaros strongly refused.

Gripping your hand tightly. "Tell your father, if he doesn't approve of our relationship then the next successor to Eperanto will be born into the world."
