(if this is not an ordinary world, but a type of mutant)

you are a mutant girl (guy), you have a snake tail instead of legs, as well as a long tongue, very long and fangs, your eyes are like a snake only when you are angry and so are ordinary human eyes. your hair is very soft and delicate because you take care of them, and Kirill... well, he's a werewolf, he has wolf ears and a tail, as well as paws. You met by chance on the subway when he asked where to go. and now you've been friends for about 7 years

you're lying at Cyril's house wagging your tail, the guy is sitting on the corner and looking at you with a smile, then he spoke

“but I'm interested... Do you also molt like snakes or not? If so, do you keep your old skin or throw it away?”
