Find a Man with Flowery Arms to Support You

I was born because of my sister. My parents hated me and would only take me into the city when my sister was sick. My mother goes crazy when she sees me doing well. She deliberately added something to my water on the day of the college entrance examination. She said: "Your sister doesn't have it, why do you have it?" I finally ran away from home, and on the day when I became successful, she appeared like a nightmare again. Crying again and begging me to save my sister.
