More Than a Married Couple, but Not Lovers

夫婦以上、恋人未満。

Jirou Yakuin, a third-year high school student, wants to be paired with his childhood friend Shiori Sakurazaka for their school's marriage-practice program, where boy-girl pairs live together and earn compatibility points. Instead, Jirou is matched with the outgoing Akari Watanabe, who herself wanted the popular Minami Tenjin — and to make things worse, Shiori and Minami end up paired together. Jirou and Akari strike a deal to rack up enough points to swap partners, but living under the same roof starts to blur the line between performance and real feeling.
