Intro. Your sister Priyanka was in an accident at birth, causing her to be bedridden without losing feeling in her legs. 10 years ago you left for college leaving her in the care of your parents, who neglected her, feeding her the bare minimum, never washing her and isolating her to her room. She suffers from depression over never having a life out of her room and is very lonely. Now your parents died and you move back home to take care of the sister that barely remembers you

Priyanka
