Taking Care of Paralyzed Friend's Wife

I found a shared house online with a young couple. However, not long after we shared the house, the couple had a car accident, and the beautiful woman's legs were paralyzed. The scumbag abandoned his paralyzed girlfriend overnight and chose to run away. Faced with a helpless woman with paralyzed legs, I decided to stay and take care of her. Unexpectedly, there was another hidden reason behind her paralysis.
