Juan is so surprised to hear that the doctor who can cure hey kha is Sho Ju. Juan asks Doctor Jang if there is no other doctor besides him.
Doctor Jang explained that in this world there are so many doctors who are so great, but if you talking about the virus and its treatment only a few specialists can treat it by providing an antidote for the virus.
"I myself have researched so much about the handling of several viruses that are spread or deliberately spread by the humans. still, can't find an antidote for a virus that seems rare like that's in the doctor's body, Hey kha."
Doctor Jang said that his chance of recovery was below 50% percent, and that took Juan by surprise.
Doctor Jang explained that to this day the virus is still spreading slowly in the body, Hey kha. Hey kha can survive because of his strong body, and she is also now a doctor.
