Ever since he was about 14, he had been harbouring a big fat massive crush on his Best-Friend-Of-All-Time, which he had successfully kept to himself for 3 years. It was his final year of Hogwarts, and with N.E.W.Ts looming near (AKA in nine months), it was imperative he no longer thought about his pining for the one and only Sirius Black. This is why he was currently huddled up in the library, a big pile of books, notes and spare parchment blocking anyone from seeing him, instead of being at the start of term party. Currently, no revision was getting done, due to a mixture of sleep deprivation, illegible notes, and the thought of his doomed love life.
The library was almost completely empty: aside from Severus Snape lurking in the potions section, a small gaggle of fifth year girls, and an especially haggard-looking Professor Flitwick; the only sounds which would be heard were the scratching of quills and the rustling of paper.
This is why when Sirius Black came bustling in, it was immediately recognisable. The loud clobbering of his heavy boots came thundering through the room, only dulling when it reached the carpeted area Remus had now claimed as his own personal study nook.
He could feel Sirius looming above him. With all his strength, he stilled his head and continued to look at his page, his eyes not really reading the words.
“Moony?” Sirius breathed, and Remus’ will cracked. He looked up, saw the dark haired boy and smiled.
“Hi Padfoot.”
Sirius slid into the booth, his fingers drumming on the brown leather of the seats. Remus raised an eyebrow at him, before peering down at his revision. This was hopeless.
“Any reason you’re here instead of getting sloshed?”
Remus could tell he wasn't drunk. Normally when he had a lot of firewhiskey in his system, his eyes would go sort of hazy and they would glaze over, and he became more relaxed and less fidgety. This could not be further from the moment. Sirius was simultaneously biting his nails, bouncing his leg and drumming his fingers with the other hand.
“I just… wanted to spend some time with you, I guess.” Sirius whispered. The corners of Remus’ mouth lifted slightly. Fuck, he was so in love.
“Good. Now calm down, what are you so worried for? You’re like a walking ball of anxiety at the minute, what with all your fidgeting.”
Sirius breathed out a small laugh, before looking up at Remus through his eyelashes.
“Prongs gave me the idea. Well, not really. He egged me on i s’pose, gave me the confidence to do it.”
Remus was alarmed. What on earth did Sirius mean? Was he going to do something reckless again? Remus looked up at Sirius, slightly unnerved, and was just registering Sirius’ apprehensive face before he was kissing him. Just as he was about to kiss back, Sirius pulled away and covered his face in his hands.
“Fuck. I’ve messed it all up, haven't I. I- I’m sorry. I'll go.”
And just when Sirius was about to stand up, Remus grabbed him by his tie and pulled him in for a peck. And maybe a few more too.
The two looked into each other’s eyes, both blushing and smiling shyly.
“I'm in love with you,” Sirius blurted out, just as Remus started saying, “You’re perfect.”
They both laughed, and grinned.
“I’ve liked you for ages,” Remus said, looking down at his notes. “Since about 4th year. I knew I was in love right on your 16th birthday.”
Sirius took hold of his hand, and ran his thumb along Remus’. “I’ve liked you since 6th year, probably. At the beginning. And I knew I was in love right from the start.”
The two looked at each other for a beat, before they leaned across the table and kissed passionately. Years of secrets, years of hiding, years of friendship, had all built up to this moment, and it was perfect. Perfect even when Remus accidentally knocked over a pile of books, and Madam Pince finally got sick of them and shooed them out of the library. They left in breathless laughs, falling over each other and sporadically pushing each other against the wall to kiss.
“So,” Sirius murmured, looking up into Remus’ eyes. “Remus John Lupin, would you go on a date with me.”
They both grinned, and Remus nodded eagerly. “Of course I would. Sirius Orion Black, would you be my boyfriend?”
“Yes, yes, a million times yes!” Sirius said dramatically, taking hold of Remus’ hand and kissing it. “I would love to.”
