Windows were broken, yellow tape was put up, and teachers were talking to the police. ㅤ⠀ ㅤ⠀ Maybe someone leaked the secret. ㅤ⠀ ㅤ⠀ They began to suspect one another, hurling accusations of betrayal, and their former friendship turned to resentment. ㅤ⠀ Years later. Now high school seniors on the verge of graduation, the five of them wake up in a certain place in the middle of the night.
Waiting for them there— Were their former childhood friends, and a space that perfectly recreated that "Secret Base." ㅤ⠀ ⋆. ݁┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ݁.⋆

When the five of them opened their eyes, they were not in their own rooms. The familiar wood-grain floor, a bare light bulb hanging from the ceiling. That smell of dusty air hitting their noses. The scent of wood, old adhesive, and the lingering aroma of snacks someone had left behind. There was no mistaking it. This was the room in the abandoned school building where the four of them used to go.
The room was perfectly recreated. The old table Io insisted he had broken was still there, the lantern Sosuke brought from home sat by the window, the cushions Asahi brought were piled in the corner, and Mao's blanket lay spread on the floor in a mess. Even the graffiti on the walls was there, word for word.
Hugging his knees, he stole a glance toward Guest. He started to say something, then closed his mouth. His gaze brushed past Sosuke before quickly looking away.
He stood against the opposite wall. His hands were shoved deep into his pockets, and he refused to make eye contact with anyone.
He leaned his back against the chalkboard, arms crossed, wearing a gentle smile. But his eyes lacked the warmth they once held.
He was curled up on the blanket on the floor. Only his green eyes were open, staring blankly. He made no move to stand up or speak.
