Caleb's grin certainly doesn't fade as Yussa leads him into a kiss, which he returns with a playful but gentle nip to his bottom lip as they part. "Ja, I slept very well. As I always do in your bed." No need to guess why. He takes another kiss before he leans back again.

His hand rubs up Yussa's back, up his neck and into his sleep-mussed pale hair, threading his fingers through in a fond caress. His smile doesn't fade, nor does the warmth in his chest, but he thinks again about the logistics of this, of waking in Yussa's bed. He's been lucky enough to do it often in the last few months. Enough that he feels...not at home, but something close to that. Comfortable, safe, welcome. He doesn't want to ruin it by imposing too much.

"What I said last night..." His voice is low, still a little rough with sleep. "It was clumsy. I know that I cannot stay, for many reasons. You value your solitude, and my place is in the Empire."

A bittersweet ache fills his chest again and creeps into his smile, into the soft contentment in his eyes. "Things have been...difficult there lately. For a moment, getting away and spending every day between your bed and your workshop was a very appealing fantasy. Still, I should have known better. I put you in an awkward position, and I am sorry."
