if he did that he might end up getting bored of life and want to wish to die already
Maybe he's already give up on his own life..... or because he is deadly ill so wishing to be healthy isn't something than can be granted.....?
Ikr lmao. He had three wishes there was room to save his life and get a lover lmao
Maybe health(life) is a wish greater than the compensation(first time of the contractor) so it's something unattainable or a wish that can't be granted even for a demon?
....Why didn’t he just wish for perfect health?
