Her past...

In the past, and before she died tragically, Luna lived with her father until she reached 14 years old. She loved him deeply,  they co-depended on each other most of the time .

And even when their financial situation was not good they managed to survive all those years, he cared for her so much and he was always there for her, she never felt that she wasn't safe, those were her happy days anyway .

And when he died in a car accident, she was forced to live with her unfaithful awful mother and her new  family. 

Her mother cheated on her father with an old rich man and ended up marrying him despite his kids' rejection. He had 3 sons and all of them were older than her .

Growing as  girl in the middle of 3 step brothers that hated her was a nightmare. She couldn't forget their bullying all her life, even when she grew up and ended up living alone by herself.
