Help me find that song !

So I remember about a vocaloid-like song with death and living in loops theme. The story is that some person is inside a loop, living the same day over and over (the day they die). They try to help a cat from being struck by a truck and got hit instead.

Colors in the clip are mostly white and red.

I don't remember anything about the lyrics or melody tho (it's been a really long time).
