Bound by Fate: The Lycan King's Redemption

"Undo your trick," he then said, and now he was dead serious. "What trick?" I asked him, and he got up. He then picked up a knife. Did he save me just so he could kill me? Wasn't leaving me for dead enough for him? He left me to die in that forest after I freed him, and now this. He then slowly cut his hand, and suddenly, I screamed in pain and looked at him. Right where he cut his hand, on his left hand, I also had the same wound. What the hell? How is it that he cut himself, and yet I also have the same wound? "This trick, you bonded us together, you stupid witch," he said, his face red with rage. "No, I didn't, that doesn't make sense" I said, and his eyes started changing colour. "Fix this now, or I will kill your entire coven. I didn't spend centuries looking for a way to be immortal just so a stupid witch could get me killed," he said, and I froze. If we are bonded together, then since I am mortal, he is technically mortal as well. If I die, then he dies as well; how did this even happen? I didn't do anything; what the hell?
