This drama was really good from the start but I felt like it has been dragged to extend the drama due to high ratings. I understand that not everyone will agree with me but it's just how I feel. Neverthelesa, I love this drama. Overflowing with romance, action, and medical scenes! Amazing casts! Superb acting! Story was amazingly fun, cute, heart-jittering, but again, I feel like the few ending episodes have been dragged or maybe I just wasn't satisfied enough because the plot of the first half was incredibly amazing. Overall, a must watch! Like seriously, action + medical, that's more than reason to watch this! Plus SJK and SHK? I don't need to say anything. I'm done. They're amazing! All of the casts were amazing! The staffs were marvelous! The production was phenomenal!
