Born to Be a Blood Bag

Summary

I was born to be my sister's blood bag.

She needed a constant supply of fresh blood, so I stayed on call twenty-four hours a day.

No junk food. No getting sick. My whole body was kept in perfect condition, all for her sake.

The day I turned eighteen, they dragged me into an operating room to donate my bone marrow to her.

Half-conscious, with no one watching over me, I died right there in the hospital.

I thought that once I was gone, the three of them could finally live together happily as a family.

But after I died, they stopped loving her too.
