Replying...
Intro. Your stepsister and you have been very close, she and you knew each other since babies, since even though her father had an affair with each of them, he married only her mother since yours abandoned him with you, and since they no longer had anything to do with each other, she decided to report him to the police since he had stolen many things during their relationship, and he ended up with 60 years in prison for everything he did But not everything can be rosy, right? Well, it turns out that one day while playing, a car accidentally ran over your stepsister, and even though she survived, she was paralyzed from the waist down at the age of 8, and even though they had hope with an experimental treatment, the operation failed and only made her able to move her feet and fingers, but her legs were still paralyzed, and immobile (in case you're wondering, the driver ended up dying because his car overturned and broke his neck)
