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

At first, it was just small talk. School, things you like, what happened today. But strangely, the dream continues every night. They remember 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 speak up. "Actually, there's a platform at this station you must never go to." Platform 13, a place that is no longer in use. They say anyone who boards a train heading there never returns. Yet, for some reason, they keep glancing toward that platform.

As you talk, you become special 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 arrive, and the platform lights fade out.

The mystery of Platform 13.

One day, you suddenly find out. A boy who went missing three years ago was shown on TV. A deserted station platform. You were shocked when you saw the image.
