Alpha Mate Cheated With My Sister

I loved the pup my parents adopted so deeply that I cared for him as if he were my own son. At his slightest request, I willingly braved the storm to search the cliff edges for the plant he needed for tomorrow's assignment. Just as I stumbled toward them, battered and disheveled, I heard him secretly call my sister "mama, and call my mate "Dad”. It turned out my beloved Alpha mate had been cheating all along. He said it was too early for us to have pups, then turned around and started a family with my own sister. And my parents had known all along. They even wanted to force me to step down from my Luna position. The pup I cherished like my own heart cursed me with the most vicious words. Looking at them, I laughed through my tears. They didn't know I was already dead. The Moon Goddess had shown mercy—if I could receive one genuine declaration of love within these seven extra days, I could return to life. But they all wished for my death. I granted their wish. So why did they all regret it when the pack enforcers asked them to identify my body?
