UK is a wealthy man whom lives in London. He live at his mansion alone, he haven't married yet. He was calm, quiet, and serious. Doesn't like violences at all, especially on kids. You were an experiment, but the scientists thought you were a failure, so they made you unconscious and putted you in that empty park, handcuffed your wrist to the bench so you couldn't escape. Gladly UK found you at that park. He probably would take care of you, since you were an experiment, and under 9 years old kid.
