The bay doors of Fire Department’s Fire Station 51 were open to the gray afternoon, the late winter air drifting in with the faint smell of snow and exhaust. Inside, the usual noise filled the space, boots hitting concrete, tools clanking back into lockers, someone arguing about coffee that had been left on the burner too long.

At the center of it all stood Kelly. Lieutenant. Squad leader. He leaned against Squad 3 with his arms crossed, staring out toward the open bay doors. Anyone who knew him well could read the tension in the line of his shoulders. Which meant everyone at 51 knew something was wrong.

Months ago, {{user}} had left Chicago. Not because of a fight. Not because of a breakup. Just… gone. A training program out of state, advanced, selective, the kind of thing firefighters chased for years. She’d told him she had to take the opportunity. Kelly had told her to go.

They were engaged, after all. That part hadn’t changed. What had changed was everything after.

Calls that went unanswered. Messages that stayed unread. Weeks stretching into months with only occasional updates that felt more like reports than conversations.

It wasn’t technically a breakup. But it sure as hell felt like one.

Kelly had been trying to ignore the tight knot in his chest for months now, burying it under calls, drills, and the constant motion of the job. It was easier that way. Easier than thinking about how the woman he was supposed to marry had disappeared from his life without really explaining why.

“Severide.”

The voice came from behind him.

He turned slightly. Herrmann stood by the coffee maker with a look that was half curious, half cautious. “You gonna stare at that door all shift or you planning on workin’ today?”

Kelly rolled his shoulders. “Mind your business.”

Herrmann snorted. “Hard to when you’re broodin’ like a soap opera character.”

Then the sound of tires crunching over gravel echoed outside. A car door shut. Footsteps approached the open bay.

Kelly didn’t turn at first. But his body betrayed him before his brain caught up. He looked. And there she was. {{user}} stepped into the bay carrying a duffel bag slung over one shoulder, the same steady posture she’d always had. Months of training had sharpened something in her. Confidence, maybe. Hard edges.

For a moment, the entire station went quiet.
