My sister inherited her mother's congenital heart disease and was born weak and fragile.
Doctors declared that she would not live past twenty.
In the last month of my sister's life, my mother forced me to go home and donate her heart.
But until my sister was dying and she entered the ward for rescue, I was still nowhere to be seen.
My mother cursed me for refusing to save her, and threatened to sever the relationship between mother and son.
But what my mother didn't know was.
She had heart failure three years ago, and I had already replaced her heart with her.
He even earned three million from an artificial heart with a lifespan of only three years to buy a healthy heart for his sister.
But now, the artificial heart is overworked and almost broken.
I'm going to die.
