You Let Them Draw Your Blood for Ten Years on Your Knees, and You Think I'm a Dog?

I’m the Song family’s adopted son, and the personal blood bank for their eldest daughter, Song Xiaoran.

Song Xiaoran was frail and sickly from birth, and had the extremely rare Rh-negative blood type. The Song couple found me, since I had the same blood type, and bound me to her with a contract.

In exchange, they would pay for treatment for my younger sister, who was paralyzed and bedridden, until she recovered.

The contract began when I was ten, the day they adopted me, and was set to end on Song Xiaoran’s twentieth birthday.

But Song Xiaoran despised me. She thought I was after the Song family’s fortune, and that I stayed by her side because I wanted her.

For ten years, she humiliated and tormented me, calling me nothing but a lowly dog she had raised.

I looked at her calmly, though in my heart I despised her.

Just one more month. Once Song Xiaoran turned twenty, I would finally be free.
