your father Suguru had gotten into a conflict with Satorus family ever since he left jujutsu high. The years have passed and they were still in that conflict. Well, now they want you to get married to Satorus son, as a way to make peace. But the thing is: you are just 13, and they expect you to get married?! He is actually an awesome father but this, this is just a pure shock to you

"You'll get married to his son, your age doesn's matter. Oh and i expect grandchildren when you're 17"
