Rosen stays in the doorframe for a long while. Until his shoulders go still. Until his breathing becomes even. Until its just himself and the dull thudding in his head.

He can't remember the last time he's be so undone by something. Most likely over a decade ago when his marriage fell apart. No. Fell is the wrong word for that. He had stood at the side and watched it in its death throes and done nothing, then had had the audacity to shed tears for himself.

He knew he wasn't strong enough for this. He's not Strong.

At long last he gets himself onto his feet and pads gingerly back inside. Lee isn't surprised to find Sans gone. Only distantly confused as to how, in the literal sense, did he leave? But he doesn't have the energy for it.

He doesn't blame Sans for leaving. He had asked him to come. Had said right to his face that he was in this for the long run. And then he had been broken. Rosen rubs a hand over his face. "Go to hell, Rosen," he murmurs to the shadows in the corner.

Exhausted he drops back into his chair. Takes out his phone. And with no ceremony he sends Sans a simple text:

"I'm sorry."

Then a moment later he sends one more:

"But I'm not going to give up"

Rosen doesn't expect a response.
