Everything changed when Harry had to transfer to North Bridge in his last year of school, suddenly being away from his boyfriend and his friends. Not only were friendships and relationships destroyed, but having to be in the presence of Louis Tomlinson every day didn't make it any easier, especially when Harry started to grow feelings he didn't intend on feeling. Or an AU where Harry and Louis' relationship was only real behind closed doors until it wasn't. [UPDATED AS OF 2024]

AU. In which Louis is Harry's scuba instructor and quite happy to provide the requested special treatment, pun fully intended. It can't be all that difficult to convince Harry that they're on the same page, right? Also, Niall and Liam may or may not be dating, and Zayn is surrounded by emotionally stunted idiots. He bears it with dignity. * zarah5 on ao3

A Red, White, and Royal Blue AU where Hollywood elite, Louis Tomlinson, finds himself falling for the closeted Prince of England.

What do you do when your best friend asks you and your (now) ex to be the best men at his destination wedding? You can either tell him the truth, tell him you're not together anymore, and deal with the consequences, or you can pretend you're still together and roll with it, just pray you don't spiral. Fake it 'til you make it. You know, for the sake of the wedding. Harry and Louis choose the latter. THIS IS NOT MY STORY!!!!! This belongs to @cherrystreet on AO3 I just find it so much better reading on wattpad so here you go..... If I wasn't allowed to publish it here I am sorry I will take it out I cut the chapters a bit shorter because they were really long.

Louis is appointed the role of Guardian Angel, and his first mission is a boy named Zayn Malik. Unfortunately, it seems that a certain Demon has gotten to him first. Or... an Angel/Demon AU where Angel Louis hates Demon Harry, but somewhere along the way that stops being so true.

and he sits there quietly with harry's headphones in his ears while his eyes begin to close, totally unaware that he's listening to the soundtrack of harry falling in love with him. or, another roadtrip au featuring harry as the misunderstood hipster, louis as the bitter psych major, liam as the one with the secret boyfriend, and niall as the one who just wants everyone to be happy. (not lowercase) italian translation: @tenerifelouis

The Begrudging Starbucks AU. The world is winter and steamed milk and creamy espresso shots. The world is a never ending queue. The world is a Starbucks logo and a pink-cheeked smile from Niall and a bored scowl from Zayn and the world is Louis watching his best mate, Liam, fall in love with their newest customer, Harry. Who may or may not be in love with Louis. The world is cruel. (this is not my work. all credits go to the author, velvetoscar on ao3)

Harry's new to college, fresh out of Catholic school and conversion therapy camp, and Louis runs the campus LGBTQIA organization.

The one where in his travels to find Swan's elusive treasure, Captain Louis Tomlinson of the Black Dagger discovers he has a stowaway onboard-a stowaway who is rather tall and pretty and pouty, and can spout off Shakespearean poetry as though he had written it. A stowaway who is also, unfortunately, secretly Louis' biggest threat. Captain Harry Styles.
