It initially confused Viktor because he thought of them as married (as K would think of it) already. K had asked him to live in his apartment, and he had not asked Viktor to move out nor did Viktor leave on his own, which probably would have constituted a divorce as K understood it. A glimmer of Viktor's old humor was able to peek through as he smiled against K's neck.

"Well, the only thing that I have to go off of is what would feel nice for a human. You will have to show me a different way for you."

Having said that, Viktor reached out to take one of K's hands and pull it back to his chest by the wrist. Once K's hand was resting against his chest, Viktor let go of his wrist and pushed his hand underneath so that K's hand was sandwiching Viktor's between his hand and his chest.
