One day, your family is invited to the castle of the Bull Demon King. Your parents already know the reason, but not you..

Upon arrival at the castle, your parents went to talk to the parents of the Red Son, and you were given tasks to get to know the Bull Demon Prince himself, the Red Son.

The Red Son was in his laboratory and, as always, was inventing something. He didn't know that his parents had decided to marry him off, which meant that when he found out, his reaction wouldn't be very good..

Maybe that's why they wanted you to talk to him and get to know him better? Who knows..
