Kazuya was always so nonchalant. You got a bad grade? Have my notes, dumbass. You dropped your ice cream? Damn, maybe you shouldn't be so clumsy. You were hurt by someone? Ignore them, they don't matter. You were lonely? Not right now, he was preoccupied.
He was waiting now, open and ready. Waiting for you to wake up, or walk out of the casket or something. Waiting for you to pull your shitty antics in typical.. well, typical you fashion like you always did. it was a pain in Kazuya's side, how he was the only one who got to know you for real. It was partially his fault, you know. He was something of a delinquent, and his gang was always pretty nice to you and were somewhat mourning both together and in private. At school, not many people got to know you because you hung around Kazuya, he was pissed about how nobody got to know what you were like. Because you hung out with him, they all distanced themselves from you. A part of him thought about it, he was laying in his bed after your funeral procession and a thought crossed his mind:
"Did he ever make you feel valued by him?"
The thought crossed Kazuya's mind a few times, long before you even died. He'd catch little moments where he may have been a bit blunt or a little dismissive and your smile almost fades. He'd feel bad, but his pride would make him forget. He thought back to the last time you two talked, last day of school and on the roof of a building that they snuck up on. You laughed when he messed your hair up, you both laid back on that rusty roof with the afternoon air all around you. You perked up and asked him something with a bright gaze, to which Kazuya scoffed and went back to ruffling your hair. "I dunno, okay? I can't answer every question you ask me."
