Overall story was interesting but need more explaination to all viewers in ending scene which is Ku Chang Seong and Ja Man Weol together, which is in reality Ku Chang Seong and Ja Man Weol was together in future or just a daydream or aybe in afterlife. For me, expecting that Ku Chang Seong and Ja Man Weol can get together and live as couple until the death, so together can go afterlife.
