The school festival was a blur of neon lights, the smell of fried dough, and the constant, rhythmic thrum of music from the gym. For Shiori, it was a battleground. She moved through the corridors in her server's kimono, her breath coming in thin, whistled snatches that she drowned out with a practiced, bright laugh.
"Ren, you're leaning again," she teased, adjusting the collar of his outfit for the tenth time that hour.
They were standing behind the Class 2-A cafe counter. Ren was staring at the menu, looking profoundly bored, but he didn't pull away when her fingers lingered near his neck. In fact, he leaned into the touch, a rare, lazy concession to the "fluff" of the moment.
"My feet hurt," he complained, though there was a hint of a smile. "How do you have this much energy? You've been running since 8:00 AM."
"I told you," she whispered, her voice cracking slightly. "I'm the chaser. I don't get to be tired."
"Well, stop for five minutes. Sit." He pulled a stool over with his foot and nudged her toward it.
They sat behind the counter, hidden by the decorative bamboo screens. For a few minutes, the world outside—the shouting students, the clatter of plates—felt like a distant dream. Ren reached into his pocket and pulled out a small, crumpled paper bag.
"Here," he said, shoving it toward her. "I found the booth selling those handmade bookmarks. You said you liked the blue ones."
Shiori's heart didn't just race; it stumbled. She took the bag, her fingers trembling as she pulled out a delicate, hand-pressed leaf encased in glass. It was beautiful. It was a "gift." To anyone else, it was a sign. To Ren, it was just something he'd picked up because he was bored.
"Ren... thank you."
"Don't make it weird," he mumbled, looking away. "It was like 200 yen."
"Still." She held the bookmark against her chest, right over the spot where the pain was the sharpest. "I'll keep it forever."
"Forever is a long time for a piece of glass, Shiori."
"Not for me," she said softly.
The "fluff" reached its peak that evening. After the festival ended, they stood on the school balcony, watching the cleanup crew below. The air was cooling, and the sky was a deep, bruised purple.
"Hey," Ren said, breaking the silence. "Next year... let's do a haunted house. Less walking, more sitting in the dark."
Shiori looked at him. He was looking at the horizon, already planning a future that included her by default. He wasn't saying he loved her. He was saying he expected her to be there—a permanent fixture in his life, a bookmark he'd never actually move.
"Next year," she repeated. The words felt like lead in her mouth.
She felt the familiar itch in her lungs. She turned away, coughing into a handkerchief she had kept hidden in her sleeve. When she looked down, the white fabric was almost entirely soaked in that deep, ink-red.
"Shiori? You okay?" Ren asked, turning toward her.
"Just... the dust from the festival," she lied, her voice a ghost of itself. She tucked the bloody cloth away and looked at him, memorizing the way the twilight hit his eyes.
"I'm fine, Ren. I'm always fine."
She walked away first this time, the blue bookmark clutched tightly in her hand. She had reached the peak of the chase. She had the gift, the promise of "next year," and the warmth of his concern.
But as she descended the stairs, her vision flickered and went dark for a heartbeat. She realized then that the "fluff" was over. She had spent every last drop of her ink to write a story he would only start reading once the book was closed.
