ANONS, i need halp
there was once a song that now reminds me of a childhood pooping time but i cant remember in which anime ost it was
the vidao starts with a girl playing on piano, thats all i can remember, i do not know if it was opening or ending
i can also remember it was just about stars or any other romantic crap
First of all, this isn't the place. Second of all, as you seem young, I'd say Angel Beats.
It's from the anime adaptation of Wolf Guy. I'd recommend you read the manga. It's excellent.
