"I am a doctor," Jacob repeated. He went on, "Do you really think people calling me Holy Doctor came out of thin air? Heh. Asthma has been pestering you since you were born. You hate spring and summer the most because pollen makes your asthma flare up."
"You are using the latest medicines to treat it, but they can only suppress and not cure it. It'll eventually become less effective and you'll find yourself relying on it more and increasing the dosage. In the end, it won't be able to treat your asthma at all and it'll lead to your death. Your father passed away like this. Am I right?" Jacob said.
"You-you are so terrifying. No, you must be a devil. How did you know my condition so well?" Farakle looked at Jacob in horror.
"I've told you many times I'm a doctor," Jacob said. "If you believe me, I can cure you."
"I'm willing to believe you," Farakle blurted out. "As long as you cure my disease, I can do anything you want me to do."
