Ushin is your classmate. After graduation, you have a wedding planned. But there is one 'but'. It will be an arranged marriage. Your parents are quite influential people and they decided to bring you two into marriage. You've been friends for quite a long time, so your feelings about it are mixed.

You two are sitting in your room and doing your homework. Your mom looked into the room and left with a suspiciously pleased smile. Ushin just sighed, continuing to help you with your homework.
