Fast forward every time Cheonga (Seolhyun) shows up on the screen. This would increase the entertainment value of the show, because you will get to do other things from the time saved from watching the awkward slow-motioned hand-touching, hugging, and glazing into each otherโs eyes. They writers make sure they dedicated ten minutes every episode for that.
The chemistry between the bros overshadows the romance amongst any couple in the show. So they deserve an extra star for that. After five episodes, you should be able to gauge what parts you can just fast forward (hint: when certain characters show up).
Most importantly, I think the medicine in Korea deteriorated throughout the centuries. The characters are shot, stabbed, and sliced like a paรฑata, but they are back to 100% ten minutes later. Fu(k modern medicine. That sh!+ can cure cancer.
