You're my best friend
I just got my hair cut and I’m feeling overly emotional, and I don’t know how these two things relate, but here have some sterek.
They have been together for a while now. They just got their first apartment together, and saying that both of them were high on love (for each other) and hope (for a new happy life) would be quite the understatement.
There had been a time when either of them had thought that they could never have the other, that after Derek left they would never find each other again, and they had never even thought possible that one day they could have a place, a home together. And yet, here they were.
They just finished mounting their new bed, and Stiles falls on the bare mattress with a satisfied “oof” Derek following shortly after him.
And it’s then that somehow it hits Stiles. It hits him so hard and so suddenly that he’s so overwhelmed with it that his eyes burn and he wants to yell it at the top of his lungs, but at the same time the emotion is so strong that clogs up his throat, and he can barely manage to speak.
So, he just makes a small noise (all he can muster right now) and rolls over to Derek’s side, throwing one arm over Derek’s body and burying his face into Derek’s neck.
Derek huffs out a surprised laugh, but promptly starts rubbing his back soothingly.
“Derek,” Stiles mumbles, when he finds his voice again.
Derek hums questioningly and Stiles hugs him close, a little bit tighter, before he gets out of his hiding spot and looks up at his boyfriend.
“You’re my best friend.” He says, all intense, earnest and sincere eyes.
Because it’s true. Yes, Scott is the friend he knew longer, they had their high and lows and highs again, and he’s like a brother, but that’s just it, Scott is his brother.
Derek is his best friend.
Derek is the person that he thinks about first when he’s thought of a stupid joke and wants to share it with someone. Derek is the one he looks for when he wants to tell someone about what his favourite character is going through, even if it’s a show or a book that Derek hasn’t watched yet. Derek is the name on his lips when he wants to tell or show someone how he managed to do something, even if it’s just as ordinary and banal as Stiles managing to doodle a real-looking wolf shadow, he knows that even if his first reaction would be to roll his eyes, he’d do so smiling in that warm way that always tell Stiles so many things. Like how loved he is, and how Derek is proud of him, even for the little things. And Derek is the one that he glances up to look at before he even knows why.
And that’s why he hates fighting with him so much, because he’s fighting with his boyfriend and best friend. And really, there’s no one in his life that can match with everything that Derek means to him. Derek is his special person, everyone has their special person, don’t they?
And Derek is Stiles’ person.
And yes, Derek is his boyfriend, and they had already said their ‘I love you’s to each other a long time ago, but Derek is also, and maybe most importantly, Stiles’ best friend too, and Stiles really needs him to know that.
“You’re my best friend,” he repeats, because he needs him to understand.
And of course, because Derek is his everything plus his best friend, smiles small and understanding, before he leans down to kiss him on the corner of his mouth, feather-light and all softness, and whispers “you’re my best friend, too.”
And Stiles knows that Derek understands, because he can see in his eyes that Stiles is his person too.
