A Promise to Keep (An Attack on Titan Fanfic...
"Promise me that you will take care of her." Those were the last words that squad leader, Hanji Zoe had heard from her younger sister, Anna, before she gave up her last breath. "Don't worry, Anna, I promise you that I'll raise her as if she were my own." She vowed to the blond who was now laying still and lifeless on her deathbed. She heard a shrill cry of a child and walked over to the wooden crib beside her sister's bed and picked up the newborn baby and began to rock her gently, "Shh, its okay, auntie Hanji's here, auntie's got you. I promise you that I'll take care of you." The blond child finally quieted down, Hanji looked at the now sleeping infant in her arms. "I'll make sure that nothing ever happens to you."
Many years have passed and it seems that the promise that Hanji kept was entirely forgotten, she gave her niece to the child's father, who willingly took the child. Little did she know that her promise was already broken when she gave the child to him.
