Rainy (from Twilight Syndrome トワイライトシンドローム)

Rainy :
a song heard from the game Twilight Syndrome トワイライトシンドローム 探索編 in 1996, Chapter 3, on PS1
In that chapter, a female high school student suicided by hanging herself in the music room on a rainy day just to revenge to her music teacher. The male music teacher had an affair with that girl and taught her the song "Rainy". After her death, strange things happened.

May be it is superstitious, every time I played this piece, it rained on the next day -_-
