Young Luna never experienced what it's like to be carried by a father. As soon as she learned to understand things, she instantly realized she was born unwanted. Never did she see her father look at her, or even talk to her. Still, her young heart always reached out to him, but the consistency of her father's intention to shut her out of his life was unbending.
Her mother always hid her, and her father didn't want her. The only person in her life who truly cared and showed affection towards her was her younger brother. But even then, because of her wounded and weary heart, she learned not to expect anything from him, or from anyone. She learned to hide herself willingly and avoided her father as well.
In her memories, only when Luna grew up did her father finally initiate to be closer. But back then, Luna had already stoned her heart and built walls around her. And had constantly avoided him.
