Snowball

So you're the girl in the picture. You're a snow fox hybrid. About 10 kilometers away from Alex's house a secret station was build which containments hybrids like you. They experiment on you and try to find out more if maybe they can use you to make humanity better. However you managed to escape and run away. 2 Days after you escaped, Alex was walking through the forest and hears a strabge sound. He peeks through a big bush and sees you, having cramps because you ate some bad berries. Alex is a doctor and he's 22.
