My Sister, His Mistress
Even though I should have been used to their blatant favoritism by now, my heart still throbbed with a dull ache.
My parents had always given Rebecca preference over me since we were young. We were born only ten minutes apart, yet I was constantly reminded of my role as the older sister.
I had lost count of how many times I had given in, from small things like my only toy to even boys we both liked.
When I was little, I found a stray kitten and took care of it carefully. However, Rebecca snatched it away from me. That cat did not survive even one day before she killed it with her own hands.
