The silence of the morning was no longer a coincidence; it was a physical weight. Ren stood by the lockers for ten minutes, then twenty. The school bell rang, a sharp, mechanical scream that signaled the end of his "normal" life.
He walked into the classroom, his eyes immediately darting to her desk. It wasn't just empty—it was clean. The textbooks, the stray pens, the little mascot keychain she'd hung from the side—all of it was gone.
"Where's Shiori?" Ren asked, his voice cracking the quiet of the pre-class chatter.
His classmates looked at him with a mixture of pity and confusion. "Ren... her parents came by this morning. They took her things. Didn't you know?"
"Know what?" Ren's heart began to hammer a frantic, irregular beat against his ribs.
"She's been in the municipal hospital since last night. They said... they said it's been a long time coming."
The world tilted. Ren didn't ask for permission. He turned and ran. He ran past the teachers, past the lockers where the canned coffee should have been, and out into the biting morning air.
The hospital smelled of bleach and cold transitions. Ren stood at the front desk, his breath coming in ragged gasps.
"Sato Shiori," he managed to say. "What room?"
The nurse looked at her computer, her expression hardening into that professional mask of sympathy. "Are you family?"
"I'm... I'm her friend. Her best friend."
The nurse hesitated, then sighed. "Room 402. But the doctors are with her. You can't go in."
Ren didn't listen. He took the stairs two at a time. When he reached the fourth floor, he saw a couple standing outside a door—a man with slumped shoulders and a woman crying silently into a handkerchief.
He stopped. He realized then that he didn't even know their names. He had spent three years being the center of Shiori's world, yet he didn't know the names of the people who had raised her. He didn't know her blood type, her favorite color when she was a child, or the name of the disease that was currently stealing her breath.
He was a stranger in the very life he had dominated.
He sat on the cold plastic chairs in the hallway, the deep ink of the hospital floor staring back at him. He pulled out his phone and looked at their last texts.
-"Lame. Who's going to help me with the English vocab now?"
The words looked monstrous. While she was gasping for air, he was complaining about homework. While she was facing the end of her book, he was annoyed that the "service" had stopped.
He reached into his pocket and felt the blue glass bookmark he had accidentally kept in his blazer. He realized why she called herself the "chaser." It wasn't because she wanted to win him over; it was because she was running out of time, and she wanted to spend every second of her remaining life looking at the one thing she loved, even if that thing never looked back.
He wasn't the protagonist of a romance. He was the bystander in a tragedy he was too arrogant to notice.
The door to Room 402 opened. A doctor stepped out, looking exhausted. Ren stood up, his legs trembling. He wanted to scream, to apologize, to tell her that he finally "saw" her.
But the doctor just shook his head slowly.
There was no movie moment. No final "I love you." There was only the sound of a heart monitor flatlining behind a closed door, and the realization that Ren had finally been caught—not by Shiori, but by the weight of a regret that had no name.
