My Mate's Regret After Removing My Heart

The day before my mating ceremony, my mother caught my soon-to-be mate Derek in a passionate embrace with my step-sister Scarlett. The anger triggered my mother's heart attack need a transplant surgery immediately Fortunately, I was compatible with my mother for a heart transplant. I decided to give her my heart and use an artificial one instead. Faced with the enormous cost of the surgery, Derek, my coward of a mate, vanished. I went to beg my step-sister Scarlett, who had married an elderly but wealthy Alpha Marcus, for help. She claimed she didn't have enough cash, yet the next day she was showing off her new enchanted moonstone necklace. In my darkest hour, Alexander Stone appeared. He was the most renowned healer and Marcus’s son，the future Alpha. He covered all the costs and offered to perform the surgery himself. When I woke up, Alexander's face was filled with regret. He told me my mother had suffered a sudden rejection reaction during surgery and passed away. He pulled my tear-stained face to his chest, declaring his love and begging me to let him care for me for eternity. Seven years into our mating bond, I accidentally overheard his conversation with his beta: "So you gave Sarah's heart to Scarlett instead, right in front of her mother? That was brutal, even for you." "What could I do? Her heart matched Scarlett's perfectly." "But we had already found a suitable donor heart! Scarlett only needed to wait half a day. Why were you so impatient?" Alexander sighed, his voice heavy with emotion: "I couldn't bear to see Scarlett suffer, not even for a second."
