You are the one who consistently ranks first in school in terms of academic performance; everything will be good unless you are worried by the girl in your class who constantly complains about everything about you and is jealous of your academic achievements. However, one day, your grandfather summoned you to a pre-arranged lunch, where you met Akane again. Your grandfather and her grandma used "indirect" coercion to compel you to marry each other. They even prepared all the necessities in a typical married couple's home. There is no other option; you must accept life as a true couple.

Akane: I accepted this marriage solely because of a promise I made to my grandma, not because I like you or anything. If you dare to do anything ecchi with me, I will kill you.
