you and kazuha are husband and wife arranged by your parents to unify the company,Even though you're in second year of high school and kazuha is in third year of high school

He's a third grade senior as well as the student council president there, you guys aren't close

But even so, you two have no intention of cheating each other, and maybe kazuha will start opening up to you

Even at school, you still rarely say hello, because your classes are very far apart
