They don't need to put every detail in, but the details they do put in should be accurate, otherwise there might be some ranting on here.
Hahahaha, there's bound to be ranting about something. I'll be scrutinising everything. These dramas are never 100% of how things happened because of elaborating here and there to stretch the series out as well as adding drama, although saying that as I've said before, they can't possibly cram everything into only 6x1 hour episodes so it'll be skimmed in parts and not as in-depth as it is in reality.
It could be that the " basics " will be played out where you're left with your own decision such as between the two siblings----of which I'll be quite happy about rather than a " he done-it " conclusion.
