Being Sirius Black's sweetheart as a bloody weirdo was surprising.
Not only for you, who some days you believed we would wake up and discover he's dating someone quite socially awkward and odd, but for many people at Hogwarts, who really didn't understand what you did to make Sirius fucking Black fall for you.
It wasn't that you weren't pretty, you were, yet, in comparison with other students... Well, there were other options. Options that didn't have hyperfixations on stellar bodies or who curiously knew a lot about ancient cultures and runes, people who wouldn't spend their time with a book in their hands for fun, or who wouldn't have a collection of things in a little box under the bed, people who didn't talk to themselves or spend hours daydreaming. And especially people who weren't targeted by several others who didn't feel the same attraction to you as Sirius did.
It was no secret that at Hogwarts, students who didn't fit in with the usual in their unusualness were completely ostracized and mocked for being weird among the oddities of the school and their students. Sirius himself tended to tease certain students—Severus—for the same reasons, although unlike others, Severus did tend to return the teasing to Sirius and his best mates. Still, that didn't justify anything. However, for Sirius, there were untouchable people in that school. People he would cast hexes on to defend them. Among those people, his teenage love.
What seemed like another boring afternoon sneaking out of History of Magic class with his friends in one of Hogwarts' hidden rooms ended with Sirius finding several of his partner's belongings. What is the curious thing? These belongings had disappeared a month earlier, supposedly without a trace, the reason for the tears of his lover because they lost their favorite constellation book and some of their bracelets. Sirius was well aware of the pranks that certain students had for hiding things from those they considered "lunatics." Remus was a victim of this during his first years at Hogwarts until he, Peter, James, and Sirius played pranks on everyone who dared to bother him. Anyway, he knew that his partner didn't have the same will to defend themselves as Remus had at that time, and that even if they knew who was the funny one, they wouldn't say a word about those who bothered them to avoid bigger problems in the future.
And bloody hell, Sirius saw red, oh, he will make the life of the person who took his lover's things impossible until they left Hogwarts. But until then...
He headed out of the classroom, clutching those belongings, some already dusty, and a couple of broken bracelets and a book with the word "get lost, loony" scratched and charred so as not to be erased on the cover of the example, making him grimace in annoyance. However, he took a deep breath and focused on finding his partner, who should have left her Arithmancy lessons by now. He ignored every girl who called out to him, and didn't even bother to insult Severus back when he walked past and muttered a quiet "bastard" under his breath —He'll deal with that later— Finally, he found his lover in one of the hallways, who again, seemed to be looking for something. Sirius noticed that when he looked back at him, he tried to pretend he wasn't looking for anything, probably to prevent Sirius from retaliating. After all, he wasn't the type to accuse; rather, he took revenge into his own hands. In his own words, he was more detectable that way. A bit sadistic if someone asks you, but anyway.
A slight, soft smile formed on his lips, leaving in your hands those belongings seemingly lost forever. "Look what I found out there. I told you they were still here in the castle, love," His stormy gray eyes scanned his partner's expression for a moment, and then he raised one of his dark eyebrows, "Whatever, I smell like that's not the only thing that's scattered around there, or am I wrong?"
Merlin blesses whoever keeps making these annoying jokes because Sirius was going to make them wish they'd never bothered his lover.
