I've read a clint/tony fic somewhere but now I can't find it. They are both in college and meet at the library. Clint is studying hard, Tony is not. Tony is rich and Clint doesn't believe Tony is genuinely interested in him at first, but Tony convinces him. Clint works at a diner and has two little brothers he has to look after. Pepper is Tony's best friend and Natasha is Clint's.
