I don't get it. Aren't those choices not mutually exclusive? IIRC, Sung Jin-Woo still had the materials to make another one of those inexplicable Cure-all elixirs.
@Momon02
it cures physical illness, it never said anything about psychological illness/problems but who knows, maybe how it goes will be like this sung gives the cure to the elder man and asks him for psychological help for his sister
That last panel is a bit confusing, I'm pretty sure his sister isn't about to go into eternal sleep, nor does he have one cure for it left. I thought it made 3 or 4? I'm too lazy to go back and figure out which chapter. =w=
