After I Died, My Sister Went Mad with Grief

After Mom died, my sister was the only family I had.

But she found me annoying and believed I was the one who had killed Mom.

When someone framed me at school, she slapped me without hearing me out and told me to die.

She found another younger brother and paid for his college education.

She treated me like dirt.

But when I died in front of her, why did she scream herself hoarse and cry until she could hardly breathe?
