I have to say that I really LOVED this K- Drama. It reminded me a little of "Crash Landing On You" which has to date, been my absolute , overall favourite
The series is actually very funny.... You will laugh and you will cry.
The chemistry between both sets of the main couples is electric and therefore, well cast.
I think I may need to watch it again and pick up on the little things I may have missed. Highly recommended. My only negative, if I needed to add one, was that I had trouble understanding the English when spoken. The accents were so thick . I think the english subtitles were still needed in those scenes.
