Her family fled Vietnam for East Germany in the 1980s, and she eventually ran an unlicensed medical clinic in Munich serving refugees and poor patients who had nowhere else to turn—work she took on largely alone while her more experienced father was absent.
Dr. Tenma found her clinic while hunting Johan Liebert, the man he was obsessed with destroying. He came looking for information about Blue Sophie's murder and walked into a scene of controlled chaos: the clinic was packed with desperately injured patients. When Tenma pointed out they needed a real hospital, she shot back that these people didn't have that option—their social status made it impossible. She was prickly about accepting help at first, but eventually let him pitch in with the procedures. As they worked, she opened up about her situation, and when Tenma finally told her he had to leave to stop someone, she was genuinely worried about what would happen to him.
She caught his arrest on the news like everyone else. She called him an "inspiration" and hoped things would work out for him somehow, given what he was dealing with.
