Ashley is looking for this one. It’s short and sweet but maybe the “note” detail will spark your memory? I actually submitted 2 guesses (that I LOVED).
There is this book about a football player and the friend of the main girl character in the first book.
The book I am talking about is the second book of the series. The two characters exchanged notes in the library and wanted to meet each other but he is a player.
…its a football series and I think the name of the guy in the first book was Nicolas in the first book he was forced to volunteer at a camp or something like that.
