The notification chimed at 9:14 a.m., the same pitch as every other. A soft tone, engineered to be calming. The Bureau had spent three years testing frequencies before settling on this one. D-flat. The sound of a relationship reaching its calculated end.

I pulled the case file.

Mercer-Yoon, Registration #4782-B. Registered eighteen months ago. The algorithm had given them exactly that: eighteen months. Not a day more. Not a day less. MERIDIAN had processed their biometric data, their attachment profiles, their hormonal baselines, and produced a number. Today was the number.

Through the glass partition, I watched the Transition Counselor deliver the notification. The woman, Yoon, sat very still. Her hands rested flat on the table, fingers spread, as if she could hold herself to the surface. The man, Mercer, stared at a point above the counselor's head. Neither of them moved for seven seconds. I counted.

Then Yoon touched the Pair Device on her wrist. The screen would read EXPIRED now. The same word on both their devices, simultaneous, synchronized. The engineering was precise.

She started to cry. He didn't.

I made a note in the file: Notification delivered. Emotional response within expected parameters. 72-hour separation window initiated.

This was the ninety-third notification I'd processed this quarter. The compliance rate held at 98.7%. Same as last quarter. Same as the one before that. The math didn't waver. That was the whole point.

I closed the file and opened the next one.

The Pattern Recognition Division occupied the seventh floor of the Bureau's central building. Glass walls, blue-lit terminals, the low vibration of servers processing forty years of relationship data three floors below us. I had worked here for six years. I knew the sound of the building the way some people knew birdsong: the ventilation rhythm, the elevator's ascending pitch, the particular silence of a data floor where nobody talked unless they had to.

My terminal displayed the quarterly analytics report. Aggregate expiry patterns, regional compliance data, MERIDIAN's ongoing calibration metrics. Numbers arranged in columns, each one representing two people who had been told their love had reached its predicted conclusion. I scanned them the way a radiologist scans a film: looking for anomalies, expecting none.

A footnote caught my eye. Page 47, bottom margin. "1.3% anomaly cohort: reclassified per directive 2041-B."

Reclassified. I'd seen this footnote before. Every quarter, the same 1.3% appeared in the margins. The couples whose relationships didn't end when MERIDIAN said they would. The ones who, statistically, should have expired and didn't. The Bureau called them noise. Background interference. The kind of irregularity that exists in any large dataset.

I scrolled past it. I always scrolled past it.

"Ninety-three this quarter." Petra Lind appeared beside my desk, two coffees in hand. She set one on my desk without asking. She always brought me coffee when the notification numbers climbed. "That's eleven more than last quarter."

"Population growth accounts for seven of those. The other four are regression to the mean."

She sat in the chair across from me, the one nobody else used. Petra was a Transition Counselor. She spent her days in the room on the other side of the glass, sitting across from people whose devices had just changed from ACTIVE to EXPIRED, helping them navigate the 72 hours they had left together.

She looked tired in the specific way that comes from carrying other people's grief on a government salary.

"The Mercer-Yoon case," she said. "She's pregnant."

I paused. "That's not in the file."

"She told me after the notification. Eight weeks." Petra's voice was careful, the way it got when she was saying something she knew I wouldn't want to hear. "She asked about an extension."

"There are no extensions."

"I know."

"The 72-hour window is absolute."

"I know, Tova."

I turned back to my screen. The numbers were still there. Clean, orderly, precise. A woman was eight weeks pregnant and her relationship had just been told to end, and the numbers didn't care, because numbers never cared. That was their value.

Petra sipped her coffee. After a while she said, "What's the longest expiry you've ever processed?"

"Forty-seven years."

"Were they happy?"

I looked at her. "That isn't what the data measures."

She looked at me a second longer than comfortable. Then she picked up her coffee and left.

I sat with the number for a while. Forty-seven years. Registration #0093-A, one of the earliest in the system. A couple who had been given nearly five decades by the algorithm and had lived every one of them. When their notification came, they were eighty-one and seventy-nine. They'd complied within the first twenty-four hours.

I'd looked at their post-expiry data once, years ago. Cortisol levels normal. Oxytocin baseline returned to pre-registration levels within three months. MERIDIAN had been right. The love had ended on schedule.

Or the measurements had.

I closed my terminal at 5:47 p.m. The building exhaled around me. Blue light dimming, servers humming their nighttime frequency.

My wrist was bare. I hadn't registered with anyone in four years. The previous device had been deactivated and returned to the Bureau after my last expiry, the way they always were. A short one. Nine months. MERIDIAN had been precise.

I'd complied. Of course I had.My parents had complied too, when I was fourteen. I'd watched them separate with the quiet efficiency the system demanded. What confused me, even then, was how quickly my father's grief seemed to resolve. Within a year, he seemed like a different person. Not recovered. Rearranged. I'd attributed it to the system working as designed.

On the way out, I passed the notification room. Empty now. The chairs pushed back. The table wiped down. Tomorrow it would fill again.

My wrist was bare. The skin where the device used to sit had long since lost its mark. I pressed my thumb against the spot out of habit. The skin was smooth. Unmarked. As if nothing had ever been measured there.

The system worked. I believed that. I had to. I'd built my career on it.

But sometimes, on nights like this, walking out of the building that calculated the end of love for a living, I wondered what the forty-seven-year couple had eaten for dinner on their last night together. If they'd spoken. If they'd sat in silence. If, in that silence, the math had felt like enough.

I walked into the evening without looking back.
