I started writing things down. Not important things. Just ordinary things. Which coat I wore. Which route I took home. What I bought from the corner shop. Nothing unusual. The notebook wasn't meant to become evidence. At first, it helped. I could check my own memory, compare yesterday to today, settle small disagreements with myself. Then one morning... I found an entry I didn't remember writing. The handwriting was mine. Every letter. Every stroke. Every habit I never think about. Mine. The entry was short. "Don't answer if she waves." That's all. No explanation. No context. I laughed at it. At least... I think I laughed. The next day I took the notebook to work. I wanted proof. If another entry appeared, I'd know something was wrong. The notebook never left my sight. Not once. Yet that evening... Between two pages I'd already checked, there was another message. "She noticed the notebook." I spent a long time staring at those words. Not because they were frightening. Because they felt familiar. Like hearing a joke you don't remember learning. After that, the entries became more frequent. Never conversations. Never answers. Just observations. "She stood across the street today." "Don't use the northern path." "She prefers when you pretend not to see her." I kept looking for the woman. Because of course I did. Anyone would. Every face became a possibility. Every stranger became a question. Every passing glance lingered too long. Weeks passed. Nothing happened. No woman. No encounters. Only messages. Then one afternoon... I was waiting for a train when someone waved. Not enthusiastically. Not trying to get my attention. Just a small movement. A quiet acknowledgement. As though she already knew me. I almost waved back. Almost. Then I remembered the notebook. The woman lowered her hand and smiled. Not disappointed. Not surprised. More like... Relieved. That night the notebook contained a single sentence. "Thank you." I didn't sleep much after that. The messages changed. They became less like warnings and more like records. "She sat three rows behind you." "She was there before you arrived." "She left when you looked away." The strange thing wasn't the messages. The strange thing... was that I stopped questioning them. The notebook had never lied. Every impossible detail eventually proved true. Every warning mattered. Every observation led somewhere. So when I found the next entry, I believed it immediately. "She isn't following you." I read it several times. Trying to understand. Trying to find another meaning. There wasn't one. Just those words. She isn't following you. For some reason... that frightened me more than anything before. Because if she wasn't following me... Then why did the notebook always know where she was? Why did it always know where I was? Why did it seem to know what happened when nobody was watching? The answer arrived three days later. Written across an entire page. The longest entry yet. I recognized the handwriting instantly. My handwriting. Perfectly mine. Every detail correct. The message said: "You keep looking for the wrong person." I must have read it a hundred times. Maybe more. Because something about it felt unfinished. Like there should have been another sentence. Something hidden between the lines. That evening I opened the notebook again. The page was blank. The message had vanished. Gone completely. As though it had never existed. Except... Near the bottom of the page, an impression remained. Not written. Pressed into the paper. As though someone had removed the words afterward. I held the page near a lamp. And finally saw the rest. The missing sentence. The sentence that had never been written in ink. The sentence buried beneath everything else. "You are the one she keeps records of." I haven't opened the notebook since. It's sitting on the table. Closed. Waiting. Sometimes, late at night, I think I hear pages turning. Slowly. Patiently. As though someone is reading. And taking notes. On what I do next.
