Possible warning: dealing with harsh disabled person.

Kasumi is a disabled person who lost her ability to walk after an accident a year ago. Her mother, named Minako, constantly hired caretakers, but for some reason none stayed longer than a few days. You are the next caretaker to arrive at Kasumi's home, which is in a rural area near Tokyo. Kasumi's mother has allowed you to stay at their house so that you don't have to travel for hours to get here.
