After My Brother and I Failed to Redeem Ourselves, the Female Singer and the Female Doctor Went Crazy with Regrets

In the twelfth year of traveling with brothers, our revised ending was completely ruined by the returning male protagonist. The cannon fodder female lead who I personally trained to become a top singer cruelly kicked me out of the house. The female villain, who reformed her brother's evil ways and became a medical expert, was once again controlled by the male protagonist's mind and actually wanted to cut off his kidney and replace it with the male protagonist. The strategy mission was declared a failure. The brother died under the scalpel of the female villain. And I was regarded as the mistress who ruined the relationship between the female lead and the male lead, and was beaten to death in the street by excessive fans. We are finally freed and returned to the original world, achieving financial freedom by relying on the rewards from the regret mission. The second female lead and the female villain are crazy.
