I Could Be the One by wadedurnt
Never had Agron expected to get close to the brother of one of his arch enemies, and neither did Nasir. They both didn't expect to get involved on a deeper level- but they make it work.
College AU! I love reading about Nagron in college! Agron & Nasir attend Capua University and, as you can imagine, high jinks ensue. Agron and Nasir's older brother belong to rival fraternities, which makes their relationship complicated, but they're determined to explore their new friendship, which is quickly becoming romantic. Of course the entire Sparty crew is in on all the fun, including our beloved Duro. I can't wait to see how this story plays out!
