Anastasia shared her story on Instagram, it was written in Russian so I'm going to try my best to translate it to English (I'm sparing you the details):
"Since I was a kid, I dreamed of being an actress and playing in films. When I was 13, I found an online modelling school that taught acting, dancing, walking runways and photography. I studied there for 6 months and after graduation, I was asked to sign a contract with a modelling agency. I participated to castings for ads and I starred in Teen Wolf. There wasn't a lot of work. Two years later, in Moscow, I found a wonderful agency, Avant Models, to which I'm still signed to, to this day. I sent them pictures of myself, had a meeting and then signed a contract with them. I couldn't work abroad because I was still studying. When I was 17, I had my first trip to Hong Kong. There, I had good experiences and did amazing pictures."
