Graduation (Larry Stylinson)

Louis, 23, moves to a new university to finish his BA degree in Music Production. He gets on brilliantly with Liam, Zayn and Niall but not Harry, 21. After a particularly bad argument Louis leaves a note under Harry's dormitory room door to apologise, and things begin to change. Louis learns that he had the completely wrong impression of Harry, and Harry begins to take a liking to the master of sass.
