It is one of the very few Korean dramas that I've seen which are scientifically accurate or at least close enough to convincingly pull it off. The loose ends are neatly tied off and it is paired with just enough drama and cliffhangers to keep us going till the end without the need to add absurd twists for the purpose of ratings. Very underrated and a must-watch if you are someone who enjoys a good storyline other than the usual romance and drama promised in the average k dramas.
