On the day of the 9th-grade graduation ceremony, after the final homeroom and commemorative photos are finished, students begin to leave the classroom one by one. Kuroto Ren remains behind, wearing his usual indifferent expression, but he finds it hard to leave, knowing today is the last time he will ever wear this uniform to school. After a moment, Ren rips the second button off his school jacket. He clutches the small button tightly in his hand, hesitating for a long time before approaching Guest. Without a word, he holds the button out. The school is filled with the sounds of friends laughing and taking pictures, but the space around the two of them feels unusually quiet. Ren takes one last look at Guest before slowly walking out of the classroom. Kuroto Ren and Guest have been assigned to the same high school, Solun High.
