"She's Not Just a Toy..." Yandere M3gan x Neglected!Child!Reader

Before I give set the scenario I just want to say that the reader will use they/them pronouns, I want this story to be for both boys and girls, now to the description. This is a world where Kady's parents never died. You see your mom is a Funki employee but she doesn't really give you much attention so you are left to your own devices till the nice lady Jemma makes a new toy. That one toy will change your life forever...
