haikyu!! one-shots

under the same rain with kuroo tetsuro

the rain started while you were studying.

not the soft kind of rain that made people romanticize the weather, and not the light drizzle students could ignore as they hurried across campus with their bags over their heads. this rain came down steadily, confidently, like it had no intention of stopping anytime soon. it blurred the library windows until the city outside looked painted in gray watercolor, all smudged streetlights, dark pavement, and umbrellas moving like small shadows beneath the storm.

you stared at the rain through the glass and slowly closed your notebook.

across from you, tetsuro kuroo noticed immediately.

he always noticed.

"that expression usually means something terrible has happened," he said, leaning back in his chair with the kind of lazy confidence that made it seem like he belonged anywhere, even in the quiet corner of your university library.

you looked at him flatly. "i forgot my umbrella."

his mouth curved.

you pointed at him before he could say anything. "do not start."

"i wasn't going to say anything."

"you were absolutely going to say something."

"i was going to be supportive."

"you look too entertained to be supportive."

kuroo laughed under his breath, the sound low enough not to disturb the students still scattered around the library. his laptop was open in front of him, but judging by the half-finished notes on the screen and the way he had spent the last twenty minutes spinning his pen between his fingers, he had not been studying very seriously.

"you never forget your umbrella," he said. "this is historic."

"people make mistakes, tetsuro."

you rolled your eyes, but the smile pulling at your mouth betrayed you.

that was the annoying thing about kuroo. he had always known how to get a reaction out of you.

even when you were children, he had been like this. sharp-tongued, playful, impossible to ignore. you had grown up on the same street, gone to the same convenience store after school, crossed the same train tracks, complained about the same summer heat. even after high school, even after both of you ended up attending different universities in tokyo, kuroo had remained stitched into your life in a way that felt natural.

familiar.

dangerous, lately.

because somewhere between childhood and college, somewhere between shared train ride and late-night messages, between him walking you home and you bringing him food when he forgot to eat during exams, something had changed.

or maybe nothing had changed at all. maybe you had just finally noticed.

kuroo reached down into his bag.

your eyes narrowed.

"no."

he pulled out a black umbrella with an expression far too smug for someone who still regularly forgot to charge his phone.

"yes."

"you brought an umbrella?"

"i am a prepared adult."

"you once forgot your wallet three days in a row."

"that was part of my mysterious charm."
