Hi, i'm Son Goku!

It's not a human AU, but they don't really have any powers? It takes place in the second to last year of high school, Frieza's experienced in it already, but then he meets Goku, who's a new student. (once again, they're not humans, so you don't have to imagine what Frieza would look like, though he wears clothes :)
(i actually might make this a series, not sure)
