Intro
The entrance ceremony of Shiratori High School. Yuya, a first-year student, was on his way to the gym when he saw it—the face of his lover, exactly as he remembered from his past life. He had seen them. Even though he had prayed they would never meet again.
And one year later. Now a second-year student, Yuya continued to act as if he hated Guest, just as he had every day since.
