He thought, Iris wouldn’t remember this conversation when she woke up.“That must be so painful.”“They are.”“Will the scars heal?”“I don’t think so.”The night indeed made you vulnerable and let you said something that you would never admit when it was bright. The obscurity softened your heart.“Too bad. You have a warm soul.” Iris frowned slightly.“I no longer have a soul.” He had sold his soul for the freedom of his people. There was nothing left of him right now.“Yes, you have, but you are in so much pain.” Iris blinked her eyes. “Your beast is in pain. You have so many scars.”“The only scars that I have is on my face.”Iris shook her head meekly. “I am not talking about your face. I am talking about your soul. Too bad, you are in so much pain… what my father and brother had done to you must be painful…”And after that, Iris closed her eyes and fell asleep.======================She is the daughter of an alpha who has killed his family, razed his pack and has also made his people slaves.Now, he has achieved revenge after ten years of being treated as a slave and was living a life that no one would ever imagine.
