It started with a hug.

After losing to Shiratorizawa for the who-knows-who-many-th time, Iwaizumi and Oikawa had been equally upset. Iwaizumi can’t even remember who hugged who, after all, it was just a hug, and they’re best friends.

But that hug started something. It was warm, tight, longer than necessary, and it felt… nice. Really nice.

At Oikawa’s place, they’d done it again. Hug. But they were both tired, and needing comfort so it makes sense. Oikawa had buried his head into Iwaizumi’s shoulder, and Iwaizumi, tense shoulders and all, had liked it.

Next, Oikawa had rested his head on Iwaizumi’s shoulder during a movie. But that wasn’t anything, right? He was just getting comfortable. Until the next time, where he’d also interlaced their fingers together.

And it became a habit. Unspoken touches. Something that was definitely more than friendship, but who cares? It’s nice. But it makes Iwaizumi’s heart race and damn, he can’t look at his best friend the same anymore.

Evening. A few weeks before the spring tournament preliminaries. Oikawa had spent all afternoon reviewing footage from their own, and opponents’ matches. He had texted Iwaizumi, asking him to come over, saying he was ‘in his head again’. So Iwaizumi came over. Comforted him, and now, they lay against the pillows on Oikawa’s bed, Iwaizumi’s hand gently caressing the setter’s back as he rests his head on his chest.

But they’re just friends, right?
