The Subway Stops at the Thirteenth Station

There are only twelve stations on the Arashikawa subway map. But some late nights, the last train will stop at a non-existent 13th stop. After his mother passed away, Lin Wu saw his brother there who had been missing for fifteen years. She chased him all the way deeper, only to realize that it was not just one person who was held captive by that platform, but the deleted names and truths of the entire city.
