I would probably give this a 9-9.5 rating if not for the main baddie and the non-Korean international interactions <_< >_> My husband calls John Mayer "comically evil", and I'd have to agree. The non-Korean international interactions undercuts the serious scenes, due to the acting.

Otherwise, the rest of the cast and their relationships are just wonderful. I'm glad Ha Ji Won's Kim Hang Ah doesn't end her badassery after the engagement, as could happen in other dramas. The growth of the other characters is touching. Lee Seung Gi shines as he showcases his growth as an actor. The older actors are always love. Lee Yoon Ji and Jo Jung Seok are heartbreakingly great. So much to say! But, I should stop for now...

Some plot points are far-fetched and can get repetitive, but I accept them as a driver for progressing the plot.

The OST is great and elevates the scenes.
