Prompt: Touka getting the wrong idea with Mutsuki and Kaneki?

He is hesitant and Touka is quick to tell as always. It isn't hard to tell actually; the shadow around his tired eyes deeper than she last remembered. Sullen and unsure and he is her lover. Or at least she is quite sure of it.

"What? Something hard to say?"

Kaneki looks at her nervously, her acute hearing picking up on his rapid heartbeat and shoulders tensing more than usual. "Yeah, sorta…"

Ah.

"Found a girl you like or something?"

They were living together for at least 2 years or so it wouldn't be surprising…

"No, not that!"

Ah, she thinks in relief. In that case...

"I-I'm pregnant, probably."
