GravityRain

Background
"GravityRain" is an original song by Tiara featuring Hatsune Miku.

The music video stars off with a depressed girl sitting on the edge of a building possibly contemplating suicide. A boy comes along to give her that salvation. Or possibly revenge seeing the boy hold a gun up to the girl in multiple shots. The connection between these two people isn't clear.

This song is featured in Tiara's album, TIARA.
