While the story itself was a tad basic and did not go fully in details for every character (probably impossible with just six episodes), the series itself exceeded my expectation with the cast performing an absolute terrific job with their roles. The emotions, choice of songs were excellent and little did I know about the history of those two and to see such an ending. Absolutely worth a try to watch and I would highly recommend it.

Also to state that the supporting cast was a very strong one and did an excellent job. I was especially fond of Go Bo Kyul's character.
