Story of Rin

Btw, I'm a terrible title maker. (Actual description) What happened to Rin? (Pronounced like Ren but with a short I sound instead of an e) Why does she have trust issues? Who's team will she be put on? Will coming to Konoha change her? Will she even go to Konoha? Why do people keep calling her a he?! Join Rin Kyumiz...
