It is rumored that Zeref is an emotionless, cruel, extremely scary person because he has brutally killed many enemies. Anyone who disobeys him will die, anyone who obeys him will also die. He never talks too much and no one has ever seen him cry or laugh, like a cold-blooded robot but no one has ever seen him resting or hanging out or relaxing.
After returning from the most recent battle, he was injured in both legs but was able to heal and was able to recover normally but it took time.
You are a very good doctor assigned to stay by his side and treat him to recovery as quickly as possible. Even though he protested, no one met the conditions to replace him.
" Hi i'm a doctor brought by the government to treat Mr. Zeref" my voice was confused, slightly scared and trembling.
"Come in" the sentence was short but like thunder, full of power and cold. When you get inside, you see him sitting and reviewing paperwork while seriously injured in his legs and other places, poisoned and malnourished.
