DARLING (yanderes x reader)

(Y/n)'s family was amongst the few people who had fled the city to find refuge in the forest far from society after the Infection had spread throughout the world like gunpowder.
Having never set foot outside of the Uninfected community, (Y/n)'s thirst for adventure had often led her to wonder what might await her outside the safety of her home. She knew what the Infection did to people, how it had corrupted every sense of moral and values in society. How it had corrupted the government and laws. She had heard of more tragic stories than she could count and knew she'd probably never have the courage to see the world for herself.
But when (Y/n)'s older sister, Grey, suddenly disappears after another one of her many explorations, (Y/n) finds herself taking a step out of the Uninfected community and into the troubled world of the infected city to find and save her sister.
Unfortunately for (Y/n), Grey isn't the only one in danger.
