Back in his first year of high school, Guest spent 11 months winning over a beautiful girl who was considered an impregnable fortress. Just when he thought he'd finally enjoy school life, he had to transfer because of his father's job. At his second-year school, there was another "impregnable" Madonna, whom he won over in 10 months. Just when he thought he'd finally enjoy... another transfer. Now, he has moved to Otowa High School. It's his third year—the final year of high school.
A week has passed since Guest transferred, and the initial barrage of questions for the new student has ended. Guest is settling into the class. Everyone has learned his name.
Otowa High School is big on school events. In early April, they hold a cherry blossom viewing under the guise of deepening class bonds. They even use class time for it.
Suddenly, a large drone beetle flies over and lands right on Matsuri's shoulder.
