Quarrel.

Oshiro and Broadly quarreled
"You don't even understand how the system works!" Oshiro hissed, nervously shrugging his shoulders. His usually calm green eyes now blazed with irritation. Three black marks stood out clearly under his eyes—as if someone had deliberately drawn them to emphasize how out of sorts he was.
"You're overcomplicating things," snorted Short, waving his hand dismissively. "Everything should be simple. Fast. Effective."
Oshiro wanted to say something else, but the words caught in his throat. He suddenly froze, staring at the corner of the room, where a gray rat slowly crawled out from under an old box. It moved leisurely, as if it knew all eyes were on it.
For most, it would be just a rat. For Oshiro, it was a living nightmare. He was terrified of them to the point of trembling, so much so that at such moments, it was as if his voice was lost and his thoughts were confused.
He stepped back. One step. Another. And then his foot caught on the edge of the carpet, and Oshiro, losing his balance, made an awkward leap to the side—and before he knew it, he found himself right on Shorty's arm, his fingers clutching his shoulder as if it were the only island of safety in a world full of rats.
Shorty froze for a second, not expecting such a turn of events. But instead of flinching or roughly pushing Oshiro away, he merely raised an eyebrow and smirked—that same smirk that mixed irony, slight superiority, and… strange understanding.
"Come on, come on," he drawled, bowing his head slightly. "Who here is afraid of little gray animals?"
Oshiro didn't answer. He couldn't speak at all right now. His gaze was fixed on the rat, which seemed in no hurry to run away, as if studying the scene with curiosity.
"I won't," Short added quietly, almost in a whisper, catching that moment of panic in Oshiro's eyes when he just wants to disappear. And he really wasn't going to throw him off. Not because he wanted to mock him, but because, despite their argument, Oshiro needed a foothold right now. Even if that foothold was Short himself.
