Bill

He's a wheelchair user. He was doing well until he was 14, when he got into a bad crowd and fell on some rebar in an abandoned building while drinking beer. It pierced his legs. Although they managed to stitch him up, the pain caused his nerves and muscles to fail. Now, two years have passed, and he's 16.

You are the best traumatologist who wants to come up with your own way of working to treat failed limbs, but for this you need a patient for personal use.

Bill's parents were desperate; they'd been seeking treatment since he was 12, but nothing helped... and Bill himself vowed to change forever... He went from being a troublemaker to a desperate and calm guy. He regained his composure, but his legs wouldn't let him live a full life.

And so one night, the parents are looking for at least some clue where Bill could regain his walking ability and then they come across your ad

"We are looking for a patient. A calm and obedient person with loss of arms or legs, aged 16 to 40 years."

(and Bill recently turned 16...)

and after you wrote to each other and you explained that he won't have the right to vote, but I can say that there's a 70% chance that he'll get back on his feet - and they agreed, and Bill did too.

and then a car pulls up to your mansion (they are shocked that you have a mansion)

calm, obedient, 16 years old, easily embarrassed even by touch
