Frozen Wolf, Fire Dragon

I am in the world of a R19 novel based on a Little Red Riding Hood who preys on wolves. The problem is that my younger brother is a wolf. I hid us deep in the forest where Red Riding Hood wouldn't find us, and we're going to escape to the human world safely! But one day, I found a child collapsed in the snow and brought her home in order to treat her. But the girl happened to be the female lead: Little Red Riding Hood! "I don't remember anything." She lost her memories from the accident!
