I truly enjoyed this all the way through. I found it witty and charming. Strong character personalities for both lead roles, with well balanced second leads. The scenes with the two pairs together were so much fun. Loads of amazing and fleshed out supporting chars with great Korean actors and "so so" international cast. Not a story about finding love and the struggle of getting together, but a story about how to make it work to stay together. Also, a military drama disguised as a medical... Nah, this was straight up a romantic comedy with some sprinkles of action and suspense. Nonetheless extremely engaging and entertaining. A must watch!
