“It’s bonding,” Aris whispered. “The engineered yeast is producing the targeted compound. If my calculations are right, this version will only activate in the presence of a genetically matched partner’s skin microbiota.”
“I built a proof of concept ,” she corrected, though her heart was hammering. “It’s not for humans. It’s for—look, the grant said ‘novel approaches to pair-bonding in isolated populations.’ Mars missions. Submarines. Whatever.”

“You designed the receptor target based on your own HLA haplotypes and mine.” He didn’t blink. “I saw the notebook, Aris. Page ninety-three. You ran the compatibility algorithm last month. You just didn’t tell me.”
