My Brother Faked His Death to Trick Me into Donating a Kidney, So I Sent My Whole Family to the Crematorium

Dad was diagnosed with acute kidney failure and needed a transplant. The family unanimously decided that I would pay for it and my older brother would donate a kidney. On the eve of the surgery, my brother suddenly died, leaving me as the only matching donor. After donating my kidney, I worked nonstop to pay off my debts. But five years later, my brother somehow came back from the dead and returned home. Meanwhile, worn down by the surgery and overwork, I was plagued by illness and cruelly kicked out by my parents. In the end, I died miserably on the street. When I opened my eyes again, I was back on the day my brother had suddenly died. This time, I was going to send my whole family to their graves!
