Anna's birth and the eleven years of her life were designed. In order to save the life of her sister Kate, Mom and Dad did IVF and gave birth to Anna as Kate's backup transplant library.

Kate was diagnosed with acute promyelocytic leukemia at an early age.
Kate's health could have problems at any time, and in order to keep Kate alive, Sarah quit her job as a lawyer, and Aunt Kelly had to do some part-time work.
Kate's leukemia has been recurrent, but the most serious is not her leukemia, but her kidney failure problem.
Sarah asks her eleven-year-old daughter Anna to donate her kidney to save her sister Kate's life.
Leaving aside how painful the surgery was for an eleven-year-old girl, anna would never be able to exercise, join the cheerleaders, or even get pregnant and drink, and live carefully for the rest of her life.
My father was busy working all day to make ends meet. For Kate's sake, the mother did not care about Anna's feelings and arranged everything alone.
In order to rebel against her mother, Anna sold her 14K gold necklace, used it as a lawyer's fee, and went into Alexander's office and asked him to be her own defense lawyer.
Alexander saw Anna's medical records and took up her case.
Sarah was furious after receiving the court's notice. She blamed Anna for being so cruel that she watched her sister dying, but let it go. During the argument with Anna, she slapped Anna in the face.
Sarah went to Alexander's lawyer's office and asked him to drop the charges against him.
During anna's eleven years, she underwent eight hospitalizations, six catheter insertions, two bone marrow aspiration surgeries, and two stem cell clearances. Leaving aside side effects such as bleeding, infections, abrasions, etc., injections of hormones that promote growth, drugs to relieve vomiting, and pain-relieving tranquilizers and sustained-release sleeping pills are not suitable for prepubertal children.
Alexander refused Sarah's request, insisting on defending Anna's rights.
Leukemia took Kate's health and made her lose her delicate face. She was exhausted all day and accepted the strange eyes of outsiders. She knew she was going to die. This is the outcome that everyone expected. Kate was not afraid of death and endured the pain of illness, but she did not want her family to suffer with her.
Since Kate fell ill, Mom and Dad have given her all their love and care, and have to send Jesse, who has a language barrier, to boarding school.
Her mother gave up her job, marriage and other children for her, and spent every day with her to fight the disease. But the ending had already doomed her to lose.
In the fourteen years that Mom struggled with the disease, Dad lost his favorite.
As an older sister, she did not take good care of her little sister Anna, but let her guard herself with her life.
She was glad she met her handsome boyfriend, Taylor. They met and fell in love in the hospital.
She can also date, kiss, and share experiences with her sister like a normal girl.
At the hospital's patient ball, she showed Taylor the most beautiful version of herself, and that night they sneaked out of the ball and had a relationship in a small room.
For the days that followed, Kate didn't get a call from Taylor. She cried and complained, mistaking Taylor for a negative person who cheated on feelings.
Sarah angrily approached the head nurse Alice to inquire about Tyler's whereabouts, only to learn that leukemia had taken his life the day after the ball.
Taylor's death left Kate's last hopes gone. For a long time, when her mother was away, she would hide in the house drinking, crying, yelling, dropping things, and even swallowing pills in whole bottles.
Again and again, she begged her mother to let her go, but Sarah insisted on fighting her illness.
Jesse is always the least noticed one at home, and he's not as useful to Kate as Anna. Parents can no longer put extra energy into Jesse.
As an adult, he would always spend his time in bars, but even if he went back in the middle of the night, he would not attract the attention of his family.
Like the rest of the family, he was equally concerned about his sister's condition and had always expressed his love for her in his own way.
The judge who heard Anna's case was DeSaver. After her twelve-year-old daughter was hit and killed by a drunkard, she spent six months healing her inner pain. As a mother, will she make a fair judgment against Anna?
To determine whether Anna's mental judgment is clear. She interviewed Anna and scheduled the interrogation for Friday morning.
Kate's entire body system was failing, and her resistance was almost zero. Dialysis left her limbs and even blood with a fever.
Kate's attending physician, Chans, recommended Miss Swarther to Sarah. She will be more than happy to make her final condolences to Kate.
Sarah rejected all of the doctor's arrangements, insisting that Kate relax and prepare for the kidney replacement surgery.
However, if Anna did not voluntarily and the court did not have any orders, the hospital would not have the right to perform kidney replacement surgery without authorization.
Aunt Kelly was always behind her sister Sarah. To this day, she also reassures Sarah that she will slowly accept Kate's destiny.
But it's too hard for a mother to give up saving her daughter and let her die.
Dialysis left Kate physically exhausted and drowsy all day. Knowing that her time was running out, she begged her father, Brian, to take her to see the sea.
With Dr. Chans's consent, Brian took his family to the beach despite his wife's objections.
Almost everyone in court believed that Anna should donate a kidney for Kate. Her sister is in danger, and Anna is the only one who has successfully matched her.
Sarah asked Anna again and again why she couldn't compare even to a stranger, watching her sister suffer from her illness. The mother and daughter quarreled in court.
Jesse couldn't take it any longer and rushed straight to the courtroom and told the truth. Kate refused Anna's offer, and she just wanted to leave this world more decently.
Alexander could no longer support himself, ignoring the strange eyes of the others, and ran out of the courtroom and fell to the ground, convulsing. He had seizures.
The moment Anna walked into his office, he took her commission not because of money and fame, and he knew how painful it was to not be able to control his body.
To get an idea of what Kate really thinks, Judge DeSaver had a conversation with Kate.
Kate and everyone who came to see her kissed goodbye. Kate, who had already looked down on life and death, had been smiling and comforting her family, as if they were the ones who were sick.
She took out the photo album she had given to her mother, promising her that she would be all right.
Sarah, who had always been strong enough to charge for Kate, lay in her daughter's arms, sobbing like a child.
That night Kate was gone.
The court made the final decision, and Anna regained medical control of the body. They won.
After Kate left, a lot of things changed. Sarah returned to work, reopened her law firm, and business was good.
Brian retired early and devoted himself to working as a juvenile consultant on urban issues.
Jesse returned to school and received a scholarship to study painting at a good art school in New York.
Every year on Kate's birthday, they go on vacation to Montana together.
Anna fails to save her sister, but she believes that her sister will be waiting for her somewhere in heaven and that they will eventually see each other again.
