[ They are cute and domestic. Domesticity also comes with its ups and downs. That said, as Viktor presses him, Yuuri begins to fidget uncomfortably. He had wanted to let the subject drop but seeing how Viktor wasn't going to let him, he tries to find the words to explain his feelings. ]

Because it won't exist when we go back. [ Yuuri says plainly and bluntly. He doesn't know anything about whether or not people forget things when they leave but he does know that when people come back they might not remember anything that happened here.

...it would make sense that they'd forget what happened here, right? Every single moment that they've shared here—forgotten. ] Everything that we have here...it's nothing we can keep with us.

[ There's a sinking feeling that starts to not only weigh on Yuuri but the air around him too. A heavy weight—the weight of his anxieties. ]
