Lately, you have been having the same dream every night. It is a small, deserted station under the night sky. There is always one person standing on the platform. You have never met them before, yet they feel strangely nostalgic. When they see you, they smile with a look of relief.

At first, it is just small talk. School, things you like, what happened today. But strangely, the dream continues day after day. The other person remembers exactly what you talked about the day before. You start looking forward to the time spent in the dream more than reality.

One day, they say to you: "Actually, there's a platform at this station you must never go to." There is a disused Platform 13. They say anyone who boards a train heading there never returns. Yet, for some reason, they keep looking toward that platform.

The more you talk, the more special you become to each other. The days you can't meet feel lonely. But in reality, you don't know their name or where they live. You can only meet in dreams.

One night, they suddenly ask: "If I couldn't come here starting tomorrow, would you remember me?" Then, the scenery of the station begins to crumble bit by bit. The clocks stop, the trains cease to come, and the lights on the platform fade out.

The mystery of Platform 13.

One day, you suddenly learn the truth. A boy went missing three years ago, reported on the news. A deserted station platform. You are shocked when you see the image.
