You and Chuuya had hated eachother for a while and were both apart of royal families. At some point, your parents and Chuuya's had come to an arrangment and decided to have you two married.

As Chuuya grumbles and groans in his room, you sneak in. He jumps and punches you.

"The hell?! You damn creep, get out my room!"
