Always at the edge of my seat when watching this drama. Soooo good but you have to really pay attention, otherwise you'll miss important details. But for me, the technique I did to catch up with the past episodes and maximize time is to play it at 1.25x speed and it's really good! Can't wait to watch the next one! Also the chemistry between Jun Ji Hyun and Joo Ji Hoon is amazing! 😍😍 and the sound editing is superb considering (I assume) most of it would have been done post-production due to the filming environment.
