The Edge of Equilibrium

Chapter 8: System Restoration

A few minutes later, Masato came out of the bathroom in a plain black tank top that fit snugly, making the line of his shoulders stand out even more. His face looked a little fresher, water still dripping from the ends of his hair. The second he stepped into the living room, his eyes went straight to Reiji, still sitting exactly as he'd left him, hands resting neatly on his knees, spine perfectly straight, staring blankly at the low table like he was waiting for someone to kick off a scientific presentation.

The corner of Masato's mouth curved up without him meaning to.

"Have you been sitting like that this whole time?"

Reiji looked up. "Is something wrong with it?"

"Nothing's wrong." Masato shook his head, laughing quietly. "It's just... relaxing a little wouldn't hurt your reputation as a professor."

Reiji glanced down at his own posture. Nothing seemed off to him. His knees were bent at a perfect ninety degrees, his shoulders squared, his weight evenly balanced. He looked back up. "I am relaxed."

The deadpan answer pulled a short laugh out of Masato. It had been a while since he'd heard Reiji answer something this seriously when it clearly didn't call for one. Somehow, this small exchange was already loosening the tension that had been hanging in the air since Reiji walked in.

"Huh, I just realized," Masato murmured, rubbing the back of his neck, "I haven't even offered my guest anything to drink."

He turned toward the small kitchen in the corner. He opened the fridge slowly, eyes scanning the nearly bare shelves. A few beer cans on the bottom shelf, a half-empty bottle of whiskey, two eggs, a box of tofu, and a packet of instant curry mix nearly past its expiration date.

Masato sighed quietly.

"Guess my fridge is kind of pathetic."

Reiji glanced toward the kitchen too. "You don't cook much?"

"Lately?" Masato shut the fridge and leaned his hip against the counter for a moment. "More like I don't come home much."

He said it lightly, like it carried no weight at all. But Reiji went quiet. His mind ran back over the apartment he'd just walked into. The files that never got put away, the ashtray overflowing with cigarette butts, the dark circles under Masato's eyes. Suddenly, all of it read like extra data, slotting into place to complete an equation.

Masato shut the fridge after another few seconds of staring at its contents. There wasn't much to choose from besides the beer, the eggs, and that packet of curry tucked in the corner. He let out a small breath before finally turning to Reiji, still sitting perfectly upright on the sofa.

"Have you eaten?"

Reiji looked up. "Not yet."

Masato paused. He glanced at the clock, already past six, then back at the bespectacled man across the room. Not exactly a surprise. In all his years knowing Reiji, he'd lost count of how many times his friend had gotten so buried in research he forgot the most basic things.

"Figured as much," he murmured, opening a cabinet. "Whenever something's weighing on you, you always forget to eat."

Reiji didn't answer right away. He got up and walked to the kitchen, watching Masato pull a small pot from the bottom shelf. A few seconds passed before he finally spoke, flat as ever.

"I've been having trouble concentrating lately."

Masato's hand paused midair. It was a simple sentence, but strange, coming from Reiji. As far back as he could remember, the professor had almost never admitted to trouble focusing, not even on the most complicated experiments of his career.

But Masato chose not to push it. He grabbed the packet of instant curry from the cabinet and held it up a little.

"Well, think about it more after you've eaten, then. An empty stomach's no help solving anything."

The sound of water slowly coming to a boil filled the small kitchen. For the first time since Reiji had walked through the door, the silence between them stopped feeling suffocating. No mention of the missing month, no questions about why he'd suddenly shown up, no attempt to bring up their last conversation at the lab.

They simply stood there, sharing the same space, the narrow kitchen counter between them, and let a simple routine carry the weight of an awkwardness neither of them was ready to put into words yet.
