"Someone, please save me!"
"Who are you asking for help, dear?" He smiled, bringing his face closer to mine, sending a wave of terror through me.

"No, my dear. You could never be my sister. This is my revenge, and you are my enemy. You will pay for your sins," he growled, freezing me with fear.
"Please!"
“You think you can hate me just because you discovered you're more powerful? Having two useless wolves inside that shabby body won’t save you, sweetheart.”
