Hey! If anyone can help me find the title of this drama that would be great. It's an older show probably late 80s or 90s. The main character is a doctor trying to find the cure of this illness plaguing the city, he was kidnapped by these government people when he was a kid and they knocked out his friend who was blind. They reunite when they are older, but the friend who is blind gets the illness and passes away. The main guy tries to create a cure for his friend but is unsuccessful. If anyone knows the name of this drama please let me know!
