Follow the Instructions のすべてのチャプター: チャプター 1 - チャプター 10

The first message came at exactly 2:17 AM. Not 2:16. Not 2:18. 2:17. I didn’t know why that detail mattered yet… but later, I would realize nothing about that night was random. My phone vibrated once on the table. Sharp. Quick. Just enough to pull me out of sleep. I frowned, reaching for it blindly. My eyes were still half-closed when I unlocked the screen. Unknown number. One message. “Follow the instructions.” I stared at it for a few seconds, confused. No greeting. No explanation. No context. Just a command. A small laugh escaped me. “Seriously?” It had to be a joke. Or one of those scam messages people send randomly, hoping someone would respond. I was about to ignore it. Then the phone vibrated again. Another message. Same number. “You’ve been avoiding it long enough.” My smile faded. That wasn’t random. That wasn’t normal. A strange feeling crept into my chest—slow, cold, uncomfortable. Avoiding what? I sat up properly now, f

The words wouldn’t leave my mind. “You’re already being tested.” I read the note again. Then again. Like repeating it would somehow make it less real. It didn’t. If anything… it made it worse. Because now I understood something clearly. This wasn’t starting. It had already started. And I had no idea when. My phone vibrated. The sound snapped me back instantly. I looked down. New message. “Test one begins now.” My chest tightened. “Stop this,” I typed quickly. “This isn’t funny anymore.” The message delivered. Seen. No reply. For a moment, I thought maybe it was over. Maybe whoever was behind this had pushed far enough. Maybe. The phone vibrated again. “You have 5 minutes.” My breath caught. Another message followed immediately. “Leave your apartment.” I stared at the screen. “No,” I whispered. Not this time. Not again. I had already followed once. That didn’t mean I had to keep doing it. “I’m not doing anything yo

The message stayed on my screen. “Do not trust anyone.” I read it once. Then again. Like maybe it would change if I stared long enough. It didn’t. I lifted my eyes slowly. She was still standing there. Watching me. Waiting. But something had shifted. Just seconds ago, she felt like the only person who understood what was happening. Now. She felt like a risk. I hated that. Because it wasn’t my thought. It was planted. Put there by something that wanted control. “You saw it too,” I said quietly. She nodded once. Her expression didn’t change much, but her posture did. Slightly more guarded. More careful. “Yeah,” she replied. A short silence followed. Heavy. Uncomfortable. The kind that didn’t exist before. “So what now?” I asked. Her eyes studied me for a moment. Like she was trying to decide something. “Now?” she said slowly. “We decide if we listen… or if we stop.” That sounded simple. Too simple. “You’ve tried stopp

I stepped back from the mirror so fast my shoulder hit the wall. The smile was gone. My reflection looked normal again. Perfectly in sync. Perfectly still. Like nothing had happened. My breathing was uneven now. Sharp. Fast. Out of control. “No…” I whispered, shaking my head. That wasn’t real. It couldn’t be real. I forced myself to look again. Slowly. Carefully. My reflection followed exactly this time. No delay. No smile. Nothing strange. Just me. But that didn’t make it better. Because now I couldn’t trust what I had seen. Or what I was seeing. The phone vibrated. I didn’t want to check it. But I did. “Adjustment complete.” My chest tightened. “What did you do?” I typed immediately. The reply came almost instantly. “We didn’t do anything.” That answer made it worse. A lot worse. Because if they didn’t do it… Then what did? I looked back at the mirror again. Still normal. Still quiet. Still wrong. The phon

I didn’t go back to the mirror. Didn’t go back to the room. Didn’t even sit down. I just stood there in the middle of my apartment, the words looping in my head like something stuck on repeat. You were not the first. Don’t trust her. Two messages. Two warnings. And somehow… both felt real. That was the problem. This system didn’t just give orders. It created doubt. And doubt spread fast. My phone vibrated. I didn’t flinch this time. Didn’t rush. I just looked down. “You’re thinking too much.” My jaw tightened. “Maybe I’m starting to understand,” I typed. The reply came instantly. “Then prove it.” My chest tightened slightly. Prove it? Another message followed. “Test three.” I exhaled slowly. “Of course,” I muttered. Then. “Leave your apartment.” I stared at the screen. Again. Always outside. Always movement. Always pushing me forward. “Why?” I typed. A pause. Longer than usual. Then. “Because this one matters.” Something about that answer felt d
