Viktor’s scent is one of the things Yuuri finds most comforting in life. It’s a beautiful mix of vanilla, ginger and cinnamon; to Yuuri, Viktor smells like home- the one place and person he will never leave.
Yuuri’s scent is addictive, in Viktor’s opinion. There’s a faint smell of katsudon, possibly from how much his mate loves it, and it’s combined with the sweet fragrance of newly bloomed cherry blossoms and coconut.
What both of them love more than the other’s smell is when their own is noticeable amidst it. Yuuri regularly nuzzles into Viktor’s scent glands, especially when the two are embracing. Viktor, on the other hand, marks him more discreetly- for example, in practise where he can run his nose and lips over Yuuri’s neck and play it off as simple coaching.
