About half way through I realized this was a Korean version of Margaret Mitchell's "Gone with the Wind". (American book and movie). I liked Gil Chae better than Scarlet O'Hara, but Rett Butler better than Jang Hyun. Eun Jin and Yeon Jun were exactly as incipit as Melanie and Ashley.
Even the title, "My Dearest" relates to Rett's famous last words. "Frankly, my dear, I don't give damn".
Very good show, but is this plagerism?
The ending was different. In the American version Scarlet marries Rett and has a child. They are happy until the child dies accidentlly. Will this be a second season?
