I don't know the original story, so I have some guesses as to what might happen, based on the trailer for the next episode. A drawing of a sister dying, both older sisters have that flower, that is left before someone dies. Will one of the older sisters die? With that in mind, 2 of the sisters have a connection to the presidential candidate, one is a reporter investigating him, and the other is a ghost painter for his daughter. What else makes you think, that the first sister also had, perhaps the person behind the original 70 billion secret fund, was him.
I wonder why Kim Eun Sook keeps revisiting actresses she's already worked with... There are so many great actresses…
in most dramas the man is older, what's the problem with noona romance? I particularly like it, I've already finished almost all of them here on the site
Celebrity 
But both leads are really expensive lol.
