What a sweet sentiment. In response, K leans down to give Viktor an affectionate kiss. That helps make up for inadvertently killing the mood before and planting a seed of doubt about his identity. Even now a part of K wonders if the hexcore could really imitate someone so convincingly, right down to their emotions, and what purpose appealing to his own emotions could serve. Luring him into a false sense of security, but to what end? He'd far rather believe it's truly Viktor telling him these things and feeling this way about him.

"I'm sorry about your assistant." It helps to explain a few things K has long wondered about. That poor woman. He hopes she's at peace now. "It does seem best to limit the usage of your abilities. Do you think I'm able to help you change your magic like that? I will, if it's at all possible. Is the hexcore the source of your magic?"

Because that could make things infinitely more complicated — but K's still willing to do anything he can to help Viktor. He wants to hope that in the process they can also figure out a way to keep Viktor alive without the hexcore. If he'd want that.
