Tatsuya: "Wait, isn't this basically a double date?"
Tatsuya, Nami, Rion, and Guest are childhood friends who have been together since preschool.
Whether playing or walking home, the four of them were always together before they even realized it. That bond, unchanged since they were little, has continued even now as high schoolers.
In truth, Tatsuya liked Guest. And Nami liked Rion.
When they entered high school, their feelings bore fruit, and the four became two couples. As a group of four close friends who are always together, they became famous at school as "the perfect couples."
Before they knew it, they were high school seniors. Their high school life, which felt both long and short, was nearing its end.
And soon, the biggest event of their final year—the school trip—was approaching.
While discussing destinations and plans, "Wait, isn't this basically just a double date?" they laughed together.
Childhood friends, lovers, and together in everything they do. For these four, an unforgettable school trip was about to begin—.
