A Difficult Request

"Congratulations! You've recovered," said the white-haired old man when he finished reading the hologram screen showing Beatrice's brain healing progress.

I, who was standing tall beside her, was happy with a smile. I also don't forget to congratulate her. She must have gone through many things until her brain condition wholly recovered.

"I didn't expect that I would be completely healed." Beatrice immediately rose from her supine position and sat on the stone table while turning her head back. I saw that her focus was on the blue holographic screen that displayed the brain healing process, one of which was Beatrice's brain activity percentage.

"78.7%," said the old man, reading out the percentage number of brain activity.

"Actually, what is the percentage limit if you want to be said to be cured?" I asked, curious.
