Remus was walking in the forbidden forest. As a dare. James dared him to go into the woods while James and Peter went to thier detention.
It was later in thier 4th year, and Sirius was still Sirius. Remus didn't want that to change. He was ready to adapt to Sirius changes though. The only thing he really wanted to change was their Friendship.
Remus may or may not have a crush on Sirius.
It's tiny though.
Like Russia small.
Sirius accedntly slapped Remus ass during a duling match with snape. Remus had a boner for the rest of the day.
Now keep in mind Remus is wandering about the woods. Remus heard a twig snap, Remus' head shot up. He looked down and realized that he was the one who made the twig snap.
Remus sighed and lowered his wand. He kept on treading into the woods, the later it getting.

Remus heard a faint meow.His head shot up and raised his wand. A couple feet away was this tiny black kitten, with Big Black eyes. Remus lowered his wand a bit.
Could any creature that looks like a cat kill him? The cat prodded forward and rubbed around his leg.

Remus got on his knees, and held the kitten from under it's arms so that they were face to face.
"Meow." The cat meowed.
Remus's heart melted. He loved animals. He picked the cat up and headed back to the Castle. Remus hid the cat in his bag,he didn't close it because the bloody cat needs air. He dodged teachers hoping they wouldn't notice his new cat.
Remus finally got up to thier dorm, witch was thankfully empty. He placed the cat on his bed and talked to it. Not like Parsal tounge or anything like that. Just In plain old English. No Magic.

Remus decied to confess to the cat about his crush on Sirius. Some peopel might call him insane or loopy for talking to a cat for half an hour but remus just wanted to talk.
"His hair is so black it's basicly a black hole, but it's soft. It looks greasy- "

The cat glared at remus.

" but it's not. He asked me to let him once. That's how I know. But I really like him. When Professor slughorn brewed Animorta I could smell was wet dog and his stupidly sweet cologne."

If cats could raise eyebrows this cat most definitely just did.
Remus ranted a bit more.

"I really really do like him. Alot.But me and my condition..i don't want to hurt him. Like ever. So its better to just stay away I guess.. and not get close. No matter what the fuck my heart says."
Remus concluded and slumped.
The cat glared so much at his last statement it looked like it wanted to slap him.

Just then James and Peter bust into the room. They gave Remus a quizzical look before asking "where the bloody hell did you get that cat?" They kept looking at the cat.

"I found it." Remus shrugged
They shrugged and and to their beds.

I wonder what id be like to share a bed with sirius?

Remus mind asked but the
other part of his brain said

Shut the hell up. You'll never know stop torturing yourself.

Remus shook his head getting rid of thoes thoughts.
"Hey lupin?" James asked
Remus turned twords him "yeah?"
"Where's sirius?" James looked around the room.
Remus looked him in the eye "I thought he was with you..i haven't seen him all day."
They both stood up and ran out of the dorm. Mcgongall was in the comment room for some reason and asked if they were in a rush.

They told her the situation.
Mcgonagall laughed.
"He got turned into a cat. It was an accident of course. He mixed up some spells.It should wear off by tomarrow."
Mcgonally smiled and left the common room.
James and Remus looked at eachother.
"You think-"
"Yeah."
They walked back up to the commen room to see Peter already asleep and the little black cat on Sirius bed asleep as Well. James and Remus sighed and went to thier beds to see if what they thought true.

/time skip to next day/

Remus tossed and turned in his bed.
Remus finally sat up straight In his bed.James was still asleep so was Peter.
But one person was curled up in the blankets copying Remus's essay.
Sirius' black messy hair was a dam rats nest.
Remus loved it.
Hopefully he doesn't rember anything I said..
Remus thought.

Sirius locked eyes with him. Sirius walked over to Remus and grabbed his hand and dragged Remus down to the empty common room.
Remus was flustered.

"I Rember what You said remus." Sirius started.
Remus tried to protest but sirius placed his hand over his mouth.

"No talking. Hey I like you back. And what you said yesterday was sweet. And your a big sap.' Sirius blushed a bit. "And what you said about being alone is wrong. I won't let it be right. Because I like you too Remus. I like you alot."

Sirius removed his hand from Remus' mouth.
Remus blinked a couple of times.
" So does that-"
Remus was interupped by Sirius kissing him. Remus kissed back.
When they broke apart, sirius whispered "sorry."
"Don't be sorry." Remus smiled and hugged him.
They cuddled on the couch and fell asleep and that is how the others found them.
