It is a mature drama understood by those who know the pain of love. The characters are superb, enacted to perfection by the lead pair. Ji Jin-Hee is exceptional. Stunning looks, superb expressions, mature acting. Though Hye-Ran is good in her own way, the character sketch of her personality may not appeal to many. But she is real. Nothing melodramatic about the entire series. Every person fitted into their role. The final outcome was a story of real people who face challenges.
What really appealed to me was the single-minded devotion of Kang Tae Wook whose character just leaped to life because of Ji Jin-Hee who actually deserved all the awards. The finale breaks your heart. He was worth much more! I wish the makers could bring in Part 2 by reversing the end, that he did not actually die, just lost his memory. Many threads left hanging, need to be tied up.
Ready for a 2nd watch. 5/5 all-stars for Ji Jin Hee <3
