Harry Styles is new to the school but not new to everyone. Malia knows him but Harry doesn't know it. Harry owns a twitter fan account and so does Malia. They follow each other and they're what you consider 'internet best friends' but due to Malia's insecurities and the lack of liking for her name she looks like a friend of hers and is under the name 'Elena'. The fact that Harry goes to that specific school isn't very good for her since he will be seeing her friend and thinking she is Elena. Now Malia has to do everything she can so Harry doesn't find out who she really is and that might just be impossible when he is trying to find her in the world.
