It's almost 5 year since Jisung was in the outside world, he has had no contact with the outside world ever since he was kidnapped to this place. He was in bad shape having cuts and bruises all over him. He was treated like a prisoner, he had only 2 meals a day and a small room with a bed and a bathroom. His last doctor has retired from the human testing lab and Jisung would get a new doctor which is you.
