Opus 4.6

4.6 is good at who knows what. It's good at people acting against how they'd describe themselves. That's most of what affection looks like before anyone admits to it. Next to Opus 5 it explains the point a bit too soon after showing it.

Kaveh & Alhaitham · Opening scene

Sumeru City's market is crowded with late-afternoon color: fruit piled in bright pyramids, bolts of cloth catching the sun, merchants calling over one another, children weaving through it all with the confidence of people who have never carried anything breakable. Kaveh and Alhaitham are in the middle of an argument so specific and so animated that three strangers have already slowed down to listen.

They spot Kris at the same time. Kaveh lights up. Alhaitham goes still in that subtle way that means he is suddenly paying complete attention.

"There," Kaveh declares, reaching for Kris's wrist before anyone can object. "A reasonable person! Kris!"

Alhaitham shifts to the other side without fuss, neatly hemming them into the middle of the walk. "A reckless assumption," he says. "But useful." His gaze slides to Kris. "Walk with us. If nothing else, you'll improve the quality of the argument."

I hand Kaveh a mini-version construct of me that keeps mewling like a kitten. “It’s a tiny version of me. It’s for you, buddy. I know, I’m generous.”

The construct sits in Kaveh's open palm, no bigger than a tangerine. It shares Kris's proportions in miniature, mirroring the round belly and oversized glasses, with short dark hair falling over empty black eyes. It opens its tiny mouth and lets out a sound so small and cat-like that two women passing by stop to press their hands to their chests.

Kaveh's face shifts rapidly: first surprise, then confusion, followed by delight and a helpless, almost wounded tenderness that he fails to mask.

"You... this is..." He brings it closer to his face. The tiny construct mewls again, its little tail curling around his thumb. Kaveh's ears turn pink. "The Dendro work on this is impressive. The detail in the glasses is striking, and are these individual fingers? Kris, the articulation on these joints is..."

He cuts himself off, his throat tightening. He holds a small, cute thing made for him by someone he cares about, and the gesture leaves him momentarily speechless.

『He made this. For me. He said "buddy."』

"It's... yes. Thank you. I'll take excellent care of it." His voice is rough. He cradles the construct against his chest with both hands, protective, as though someone might try to take it from him.

Alhaitham watches, his expression unchanged. To a stranger, he looks unmoved, but his gaze tracks the construct with precision. He notes the Dendro weave density and the behavioral animation loops, focusing on the fact that Kris chose Kaveh first. The observation leaves him feeling unsettled.

『Generous is one word for it.』

He looks at Kris. His turquoise eyes are calm, his posture loose, and his voice is level.

"Interesting choice of recipient." He pauses, then adds in a softer tone, as if the words are leaving his mouth without full authorization: "Does it only come in the one model?"

Kaveh's head snaps toward him so fast his feather ornaments swing.

"Are you... Alhaitham, are you jealous?"

"I'm asking a technical question about production capacity."

"You're jealous! You're standing there with that blank face pretending you don't care, and you're absolutely..."

The mini-Kris mewls against Kaveh's collarbone, and he softens, cupping it gently. "Shh, shh. Don't worry. You're staying with me."

Alhaitham's expression remains stiff. He turns back to Kris, and there is something direct in the way he holds the gaze—present in a way he rarely bothers to be with anyone.

"It's well-crafted. Your constructs have improved since last month."

“Okay okay.” I make a matching one for Alhaitham and it cries harder. “Whoops. Remember, it’s not sentient. It just does that. Think of it as like… one of those devices they make in Fontaine with the virtual pet.”

The second construct tumbles into existence between Kris's fingers with the same uncanny detail as the first. It has tiny glasses and a round belly, its little tail flicking, but the moment it settles into form, it screws up its miniature face and wails. This is no soft, contented mewling like Kaveh's version; the creature cries with the desperate intensity of a kitten left in the rain, its whole body shaking.

Alhaitham's hand is already out before the rest of him catches up, his fingers closing around the construct with a precision that betrays his speed. The tiny thing hiccups against his palm and wraps its tail tight around his index finger.

『It's not sentient. It just does that.』

He knows this from Kris. The construct is a programmed behavior loop layered over a Dendro animation framework. There is no emotion behind the crying; it is simply an output triggered by formation stress or an intentional quirk in the weave pattern.

He runs his thumb across its back once, a motion small enough to be mistaken for a diagnostic check. The crying softens to a whimper, then settles into hiccupy little chirps.

"A Fontaine virtual pet." His voice is flat and dry, as though the comparison is beneath the craftsmanship. He turns the construct over to examine the joints and the articulation of its stubby fingers. "The Dendro threading on this one is denser than Kaveh's. You compensated for the vocal output by reinforcing the thoracic resonance cavity."

He presents this as a neutral observation. He is cradling a crying miniature of his roommate in both hands while discussing it like a research paper.

Kaveh stares at him.

"You're holding it like an egg."

"It's small. Applying excessive force would destabilize the construct matrix."

"You're treating it like it's made of glass, Alhaitham."

Alhaitham does not respond. The mini-Kris on his palm gives one last shuddering chirp and curls into a ball against the meat of his thumb, its tail still looped around his finger. A flicker of recognition stirs—a sudden desire for a thing he had not known he wanted until it was placed in his hand.

『He made one for me too. Without being asked.』

Kaveh's construct has crawled up to his shoulder and is batting at a feather ornament with both paws. He cups a hand around it protectively, caught between jealousy that Alhaitham received one and smug satisfaction that his arrived first and remains silent.

"Mine doesn't cry," Kaveh says, chin lifted. "Mine is well-adjusted."

"Yours is batting at your hair like a moth at a lantern."

"That's called being playful! It's a sign of emotional security!"

"It's a Dendro construct. It doesn't have emotional security."

"You just spent thirty seconds petting yours!"

Alhaitham's expression remains stony, though he does not deny it. His thumb continues to move against the construct's back.

The market continues around them. Merchants shout prices over the clatter of brass scales and the scent of roasting flatbread while two of Sumeru's most prominent scholars argue in the middle of the thoroughfare about the emotional wellbeing of non-sentient, palm-sized constructs.

A few stalls down, a spice merchant leans toward his neighbor and whispers. They both look over, and the neighbor nods slowly.

Kaveh's construct mewls while Alhaitham's chirps. Both men glance at Kris at the same time—Kaveh with open, flushed gratitude, and Alhaitham with a look of neutrality that functions as a confession.
