This drama is beautiful. Historically very accurate. Portrays the 1900s aesthetic very well. Good chemistry and excellent acting. I can't really say much because this drama was that perfect. It was surprisingly fast paced but in a good way. Sentimental scenes weren't dragged out unnecessarily. It was 3 hours of pure bliss. An excellent portrayal. Absolutely gives justice to Yun Sim deok and Kim U Jin. Since it's based on a real story I can't say much. The OSTs are excellent. After watching the drama, please check out the original Death Song by Yun Sim Deok. It's beautiful. You can practically hear the sadness in her voice. It will soon become a century old. It's beauty has been preserved through the times. The version of the Hymn of Death by Min Woohuk is also a must-watch. All the respective links are below.
