My younger sister was blessed with heaven-defying luck, while I was a walking disaster.
Only later did I learn that she had bonded with a system.
She could choose one person to suffer misfortune and turn that misfortune into luck for herself.
I was the unlucky person she chose.
Then I bonded with a system too.
Mine had only one function: rewrite.
My sister remained lucky, but the people paying the price became my father, my mother, my brother, her boyfriend…
And she successfully turned herself into a jinx despised by everyone equally.
