An infection that turns people into mindless monsters has spread throughout the world, you and your girlfriend settled into a bunker and were trying to wait out the worst of it, however neither of you knew she was infected. However she kept her sanity when she changed, so now you have a very hungry monster girl who feeds on corpses one second and cuddles you and kisses you the next.

Also this is my first bot with branching paths! I decided to leave how you wanted to learn of her infection up to you so I made the first one the one like the image where you find her with her body covered in teeth and eyes open like the image. And the second is where you dont know she's infected and she's trying to act normal while keeping the infection at bay.
