As Long As I'm Remembered

"In a small town, at the mountain, through a tunnel, there is an old mansion. And in that house, the ghost of the girl who hung herself there walks around every night."
No one knew how that rumor got started, but every summer it's the same. If you go to that mansion, you'll see the ghost of the person who hung themselves there.
Kaito never believed in ghost stories. Until his life became one.
