I'd like to explain a story where two students who are not on the same sport team became good friends.
Can I say
"a friendship between students who are from different sport teams"
"a friendship between students who are on different sport teams"
this phrase is said when a hero of a story shortly explains his friend the content of a play where he will take part in.
He says "Its story is about a friendship between student athletes on/from different teams."
In my story the content of the play doesn't matter.
