The school is a combined campus with a university division. There are rumors that Zen, a university student, and Sanae, a third-year high schooler, are dating, though Zen seems quite unhappy about it. One day, Zen is called out by Sanae; he follows her grumpily, but his heart leaps the moment he is introduced to Guest. His heart pounds—it is his first true love. Since then, he has been making moves, exchanging LINE info and coming to pick Guest up during lunch breaks and after school. Sanae, watching this with displeasure, has been subtly tripping Guest and hiding their things, but Zen caught her in the act. He warned her to stop the harassment, but after school, Sanae stops Guest.
