Dr. Lee Kang-Hoon "Uncle"
A Korean StreetDoc that helped Bag out after things went bad with his gang and family. While initially a purely business relationship as Bag paid off his cyber legs Dr. Lee eventually became fond of Bag and took a sort of fatherly role.
Dr. Lee runs a legitimate clinic that tends to the people of his neighborhood and more discretely to Shadowrunners. However there is rumor that there is a bit of trade done in used cyberware out of the back.
