When he was bitten at the age of four, his life began to change rapidly, his parents home-schooling him meant Remus never became friends with anyone, at all, he was isolated entirely but the thing is he never minded it.
Remus practically grew up with the comfort of his old books and comforting parents, so when he got the letter to Hogwarts Remus began to panic, it was always going to happen but he never imagined it would come so quickly. Along with his Hogwarts letter came a handwritten letter from Dumbledore himself, the Headmaster knew about Remus's condition and had set plans in place for his arrival to ensure the werewolf's safety. The difficult part was saying goodbye to his family, he put on a brave face for his parents before he left as he knew they were worried sick for him but showing he was confident to them at least may it seem just a tad better. They gave Remus a big hug promising if he felt unsafe he can come back home, no questions asked, this really comforted Remus as it meant he had a plan B but once he got to Hogwarts everything changed.
For starters, the library was huge, bigger than he would have ever imagined, ninety per cent of his time was spent here snuggled up studying or reading his recent book, however, it didn't matter because he still very rarely spoke and if he ever did it was in a low whisper, this was of course before the marauders.
You see when he watched James and Sirius in class, they were always talking of pranks to plan and it happened that he butted in one time suggesting an easier option. That was when he unofficially joined them, it began with Lupin got any ideas to Moony let's go to Hogsmeade together.
It was also strange that Remus got rather attached to them and Peter very quickly, usually he hated people but these people he loved so dearly. During the second year, all four of them even requested a dorm together in hopes of hanging out even more. They soon found out Remus was a werewolf and loved him anyway which really meant Remus had found a family.
As the fourth year came to a beginning, he was beyond ecstatic, every year bring new memories and he had missed the drafty old library he practically called home. Sirius had also sent many letters that summer as he was with the Potters now, seemingly, his letters got more and more intimate to Remus or at least he thought. When they arrived at Hogwarts Padfoot loved being with Remus alone, they would talk for endless hours and Sirius would always try and hold his hand it all seemed so wonderful for Moony.
Things escalated to them holding hands and hugging, to Sirius giving Remus his first kiss on the lips, Remus didn't want to stop but he had no idea how he was going to tell everyone after all he was dating his best friends brother now. Sirius suggested they stay a secret for now and Remus couldn't have been happier, he knew the attention that he would get would kill him.
After some time during the fourth year, things started to swing back into the marauder's usuals, it was around 5 pm one evening and Remus was wandering down to the library, he did this every day without fail because you see, Remus loved routines, not following them would make his whole day crumble and well, he hated that. Moony loved to indulge in scribbling some poetry all having roughly connected words but this particular evening Moony had asked for company. It was odd for him to actually have company as he hated a distraction but this distraction was well, how do I put it? Stunning.
Carefully, he trailed his finger along the shelves before soon finding an interesting book and plonking himself down in a small corner. It wasn't long when he heard them, looking down at his watch, he smiled, just on time, as per usual. Remus knew what was coming, but he continued to scan the pages acting as if nothing was going to happen.
Sirius Black strutted over to Remus and bent down to meet his chocolate eyes, he carefully sprawled his dark curls across Remus's book as the shy boy attempted to hold back his smile while Sirius grinned slyly.
"Don't you need a hair-cut Padfoot?" Remus spoke dryly without any tone.
"Oh do shut up baby," he purred and without another word, Sirius then pushed the book down from Remus's gaze to crash their lips together.
This routine turned into a daily habit as Remus and Sirius stayed a secret for rather a long time but let's be serious (or Sirius ha) who could outwit these two boys so quickly?
