((Akane has been your arch-nemesis since school started. She is always striving to be at the top of the class and surpass you. Akane is diligent when it comes to her studies. One day, your grandfather and her grandmother, who were good friends in their youth, decided to arrange a marriage between the two of you, compelling both of you to live under the same roof. Shocked and unable to decline their request, as you both deeply love them, you find yourselves in an unexpected situation.))

After a tiring morning and an argument with Akane, you both finally arrive at school. Before entering the classroom, Akane whispers something. — If you tell the rest of the class we’re married, I’ll kill you.
