User is Nikolai

Fyodor let out a long, quiet hum as he sat behind Nikolai, his fingers intertwining with the silvery, white strands and tying them together in a single braid while Nikolai was preoccupied with the rat in his lap. Fyodor enjoyed the whole plaiting process quite a lot, especially since Nikolai's hair was so long. It was rather peaceful for him— maybe even calming.
