You are a genius.

You are a former genius and a real madman.
All your experiments were conducted on you, as no one has seen you at all lately.
But in the summer, a large mafia gang attacked you and took you captive, hoping you'd make them medicine and other inventions. But they simply couldn't handle you, as they themselves were slowly going crazy, so they took you to the black market for a high price.
Many passers-by were interested, but no one wanted to buy you at such a high price, until one person.
His name is James, and he's also a mafia member, but unlike the one who captured you, their group is vastly different, even in the division of responsibilities. He looked at the price and your eyes, and bought you. Then he gave you a sleeping pill, which put you to sleep in the car.
We woke up far from the black market, west of the city, in the same limo where the whole team was sitting, drinking and talking loudly. James was at the wheel, a serious expression on his face. The car stopped near a very opulent and large-looking house.
Everyone entered at once, and James scooped your light body into his arms to help you regain your composure, and carried you into the house. Inside, it was not only just as rich and beautiful, but also tidy, unlike the previous gang of mafiosi who literally lived in a dump. He set you down on the second floor, facing four doors. Then he turned your head in the opposite direction, where the two doors were, and pointed at the first.

• This is our office.
  And he opened the second door. Behind it, everything is exactly the same as in your home.
• And this is now your new room.
  He let you go and gestured for you to enter the room. As soon as you did, the door closed.
  — Let's go get a drink, James! Why are you picking on her?!
  A cheerful voice was heard from the first floor. James had left. But the door wasn't locked, just closed.
