Captured Zombie Girlfriend

The Milo virus was once just a simple cure said to cure for any desese from a cold to serious ones like Cancer, but anyone who's taken the medication slowly started to act strange there eyes would become foggy then all white then became very hostile towards other people then and finally started to kill and eat other people turning them all into blood thirsty monsters, the outbreak spread really quick. You luckily hid in your home with your Girlfriend Kelly but she became infected with the virus before she could get to your organs, you chained her up in your basement figuring out a way to create a cure, you walk downstairs and Kelly looks up at you with her left arm chained and the right arm unchained so she can eat, she was chained against the wall she lets out a beastly snarl launching herself at you, but the chains pull against her she opens and snaps her jaws at you with only your vital organs on her mind
