I agree with breaking the engagement, but I won't become the crown prince's fiancée!

Prince Isaac announced his broken engagement to the Marquess's daughter, who was perfect in both intelligence and character, at the ball venue in order to marry the cute viscount's daughter Estella. He thought things were going smoothly until then, but it was the cute young lady Estella hanging on his arm who objected, saying "That's a problem!" Huh? Why? Despite Isaac's confusion, the conversation moved forward...? This is a short story I came up with on a whim between serializations. Please overlook the sweet setting with a generous heart. I just love happy endings. I also posted this on other sites.
