He knew it was wrong. He knew something was going to happen the next day, and it could ruin everything. But in that drunken moment, Remus found himself not caring. He made eye contact with Sirius as he pulled the random boy he was flirting with into a sensual kiss. He knew he shouldn't have done it.
As Remus woke up the next morning, he found James and Peter already up and in distress.
"What's going on?" He asked groaning
"What happened between you and Pads last night?" James retaliated seemingly annoyed
Then he remembered everything. The fight, the kiss, Sirius, everything.
"Nothing, where is he?" Remus questioned
"That's the problem, we don't know." Peter said getting dressed as fast as he could.
"What do you mean yo-" Remus started
" IT MEANS HE HASN'T BLOODY WELL BEEN SEEN SINCE YOU KISSED THAT GUY LAST NIGHT LUPIN" James screamed turning on Remus
"Let's go, James." Peter said, frustrated
"Where?" James replied harshly, still glaring at Remus as he hurried to get dressed
"The Slytherin dorms, that's where Sirius is."
"How would you know that?" Remus asked as he followed them out of the room
"He stays with Regulus when he's sad"
Remus didn't question further
Their footsteps seemed louder since it was 5 am as they went crashing through the halls, probably waking up some students, but they didn't care.
"Pureblood," Peter whispered
They stepped inside the lavish common room but wasted no time looking as they ran up to the boys dorms.
"Regulus, Regulus, Regulus.." They tiptoed looking for the name plate
"Should we knock?" James asked, looking at the other boys as they stood outside the door
"It's bloody 5am. Why would we knock?" Peter whispered sharply
Remus carefully opened the door and stepped inside. He could see Evan and Barty sharing a bed, cuddling (Rosekiller 4 life), while Regulus and Sirius were spread across the twin bed they were on. They were both snoring quietly. He slowly tiptoed over to them and shook Sirius awake.
"Hmm" He grunted, half-awake
"Hiya Pads, it's me, Moony. I'm really sorry about last night. I was half drunk and really annoyed. I know that's not an excuse, and you don't have to forgive me. I just wanted you to know how sorry I am. (Cliche ik, forgive me)
"You're right, that's not an excuse, and I am really sad that you would do that to me, but I know I would probably do the same. Maybe it'll be better if we have a break. Just a few days to clear things up." Sirius replied, whispering, now fully awake and very aware of his brother sleeping on top of him.
"Yeah, I understand. Will you- urm- are you- you g-gonna-" Remus stuttered, trying to ask if he will be coming back to the dorms
"Yes Moony, I will be coming back."
"Ok, I'll see you there then." he was feeling really awkward, so he slowly backed out of the room only to face James and Peter
"Did you fuck up?" Peter said bluntly
"Not exactly." Remus replied
"Well, at least you're both alright," James said in a softer tone
'Alright' wouldn't be the word he would use, but he sees no point in explaining that to James so he just asks if they are gonna keep standing there or go back to bed for another 2 hours.
He knows that it was wrong, but he knows deep inside, Sirius still loves him, and that's all he could ask for. They may not be a perfect couple, but that's alright because they are going to get through all the challenges together.
