Smell
One day, Kazuki realizes that Kahoko smells.
Not in any bad way, he hurriedly adds in his mind. Or with her nose, because that's just sort of obvious, seeing as she has a nose and it hasn't been broken or anything to make it stop working-
He's rambling again, he realizes. Kazuki pauses, thinking hard, and tries again.
Kahoko smells nice.
He can smell it when she dances by on occasion or when it's raining out. He smells it mostly when Kahoko's very close, though, which isn't nearly as often as he'd like.
Kazuki likes how Kahoko smells. It makes him feel safe and happy and warm inside.
Kazuki goes searching for the smell one day, to find that happy, comforting scent from some other source. He browses through fabric softeners, sniffing, sifting through soaps, smelling, checking shamppos, sampling perfumes, only to come up with naught.
Defeated, Kazuki hangs his head and drags himself back to the school, despondant. He hopes that some practice will help cheer him up, but he's not sure even that will help, now. His feet lag as he slowly climbs the stairs, his mind dully wondering where he left his trumpet last.
"...Hihara-senpai?"
Kazuki turns to see Kahoko hurrying toward him in the courtyard, her eyes concerned. "Hihara-senpai," she says, reaching him, looking up at him with wide, worried eyes. "Is... Is something wrong?"
Kazuki looks at her and bites his lip for a long momne,t before abruptly pulling her into his arms.
"Ah-! Hi-Hihara-senpai..."
Her words fade, and Kazuki can hear the blush in her voice as her arms slowly come up to hold him close. A flicker of something like a smile passes his lips, and he closes his eyes and inhales deeply, finding comfort in her smell, no longer so upset at his scent-search failure.
A flower doesn't smell as pretty after it's picked, Kazuki supposes as he pulls back and gives her a smile. He'll just have to keep coming back for more.
