But after being reincarnated as an ice magic-wielding wolf hybreed in one of her favorite stories, Eve runs into a dragon hybreed named Rahel who will kill her in the future and fall in love with her little brother, Sion. Now, Eve thinks her only hope of survival is to save enough money to move to the human world.
