The tension goes out of Yuuri instantly and Viktor's just left holding him for a moment. It's not at all that he was worried Viktor would refuse to get this for him, not with how much it's obvious he wants to. It's that Viktor's completed the circuit and the difficult thing is over. He's done it. So he takes a moment completely for himself, to just stand here and breathe in Viktor, knows he'll keep the rest of the world away, would find a way to let Yuuri stay right here for hours if he needed to.

But he really only needs about a solid ten seconds of absolute rest before he's pulling back and he can tell that Viktor's caught on, now, so it's back to the plan again. He looks skeptical for a moment, but right when Viktor's probably starting to formulate an apology he says,

"I don't know. Are you going to pick out one I like?" it's definitely a challenge.
