Celine’s Love

 Celine agreed to become Brylee’s scapegoat just to save her mother for the second time around, but she didn’t expect that her father and twin sister were only using her. When her mother committed suicide because she thought she was a burden to her, she found out that it was actually Brylee who pushed her mother to take her life. Brylee sent her mom a message that it would be better if she would be gone in the world because she’s a useless mother. Celine swore to her mom’s grave that she would exact revenge for her, and she would get the justice that she deserved no matter what. And she began her revenge by seducing her twin sister’s fiance, Sebastian Anderson.
