Clean Game by TheManyFacesofJester
When a rowdy group of soccer players wreak havoc in the small diner where Nasir washes dishes, he never thought he'd catch the eye of popular player Agron. Even though he's all aggression both on and off the field, he displays a sweetness and tenderness that's too hard for Nasir to ignore.
I really enjoyed this modern au! It's a quick read, but the author does a good job of creating the right amount of fluff and conflict, while also making Agron and Nasir complex and interesting people. Crixus is a one-note character, but I understand his role in the overall story. Definitely give this cute fic a try!
