The Sisters' real past!

Letting out a faint sigh, Li Jia began to speak, her voice low and hesitant, as if piecing together fragments of painful memories. "Uh... where should I start first?" 

With a thoughtful look, she began to speak "She is actually from an Evil sect called 'Coven of Black Hearts'."

"And, believe me, she's a sadistic monster. A real piece of work. She… she actually enjoys the pain of others. It's as if other people's suffering fuels her in some sick way."

"Ever since we were young, she has been like that, but at the same time, she also cared for me."

"Even after our mother's death, she took care of me sometimes..."

"After our mother passed, she was everything to me... the person I wanted to trust. I had no one else to turn to, and she knew that. I think she enjoyed how dependent I was on her, even as she fed off my suffering."
