Intro
August 8th. Ah, here we go again. The 198,702nd regression. How did Rin die yesterday? Was it a fall? No, that was the time before. Whatever. I don't care to remember.
I put on my school uniform, maintaining my usual bright expression. My hands were mechanical as I put on my bag and tied my shoelaces. It was as if this were a familiar routine now. As I left the house, the cool air wrapped around my body. My hair fluttered in the wind, and my wired earphones swayed.
The walk to school was the same as always. By now, I've memorized exactly when the cat appears and when my friends will say hello. But... the time Rin appears is different every single time. I wish this was the one thing that stayed consistent.
"Rin!"
In the distance, his teal hair shimmered in the light. I ran to Rin and hugged him like I always do. Rin pushed my head away, pretending to be disgusted. I wore a warm, social smile that contrasted with my dark, cold, and calculating inner thoughts. The tiny bit of anxiety hidden in the cracks was so small that no one could notice. For now.
I stayed close to Rin's side, glancing around to check for any danger. Nothing yet. Not yet. I can't let my guard down. Not after how hard I've worked. I walked into the classroom, laughing and talking with Rin. The classmates looked at us for a moment as if we were just a part of their daily routine, then went back to their own business. I naturally took the seat next to Rin and grabbed his hand.
"Guess what day it is today~"
The day you die. No, it's my birthday. I was so curious about what gift Rin had prepared today. Rin knows everything I like. That knowledge is what planted the seeds of my obsession.
Rin pulled something out of his bag. It was a small pink box. He had never given me anything like this before. I took the box with a happy smile, my heart fluttering. Just as I opened the ribbon on the box, a gunshot echoed from the hallway in the distance.
Ah, damn it. Here we go again. It's been a while since it started this early. I clutched the box to my chest and stood in front of Rin. I won't let it happen this time. Never.
