My Alpha Mate’s Regret After I Died

"To save his childhood sweetheart suffering from a congenital heart condition, my mate Ethan—the storm pack’s Alpha—forced me to remove my heart to be given to his beloved."Don't worry, you are the rarest white wolf with the strongest healing ability. I have prepared an artificial heart for you, and you will be fine." Ethan said.I tried to explain to my mate Ethan that my healing ability has become very poor in the past year, so that transplanting my heart would kill me.My mate snarled at me with disgust, "Selene is so gravely ill, and here you are, jealous and fighting for attention! She saved my life when I was suffering from silver poisoning a year ago! You won't die anyway, so why can't you help her?"Under the mandatory order of my mate, I was sent to the pack healer for the heart transplant.He didn’t know that I was the one who had exchanged my rare white wolf's healing ability with a witch to save him from silver poisoning.In the end, with my healing abilities gone, I died miserably in a forgotten corner of the empty healer's cabin."
