Perfect imperfection. He gets it. The fondness and longing in his voice says enough for Byleth to discern the meaning. He listens attentively, nodding but every thought he has drops from his mind hearing that cheeky comment. He's always delighted when Emet plays along with him, and the acknowledgement feels good.

He beams up at him from behind his little mask. He won't push too far, now isn't the time for that, but sharing a moment of conspiratorial flirtation lifts his mood even more.

They land, and he slips off reaching to capture Emet's hand in his own. He's excited to see what this will be like. The relatively plain building outside piques his intrigue even more. Squeezing that apprehended hand, he nods.

"Well then. Shall we?"

This is perfect. Exactly what he wanted. Holding hands! In public! Boyfriends!
