Both have immortal, smart, powerful, sassy (also well-dressed) ladies as the lead and unknowing male leads that get pulled into their world . Both series have paranormal aspects and a woman trying to recover memories about her past. Both love stories also develop similarly with the woman commanding the man around but then unknowingly falling in love with them instead. I think if you like one you will most likely like the other one too!
What an amazing Drama.it is actually a modern drama this supernatural series is very addictive. the plot is not for everyone. Do not watch this expecting a love story the beautiful scenery, Si Teng's stunning wardrobe, and the adorable slow-burn romance. instead of the old traditional architecture or modern skyscrapers, they filmed in Xinjiang and remote places like Shangri-la City This is about Si Teng trying to make sense of her resurrection and seeking her old power and past memory. Qin Fang is basically a tool to assist her in the modern world. The first few episodes are confusing but you have to focus because it will make sense eventually. If you are confused, it is because Si Teng was also confused. She has fragmented memories, so the plots seem fragmented as wellYOU WILL LIKE IT
Both protagonists are immortal beings who are alive for a long time ( resurrected or immortal ) only that in rattan the fl is the immortal and the ml is the human. Both dramas have fantasy elements . The vibes are very similar . comedy, fantasy, and the same themes, but with a change of gender in favor of the female lol
Although in A Korean Odyssey the supernatural character is the male lead and in Rattan it’s the female protagonist who is the supernatural being, the relationship between the leads is somewhat similar and watching Rattan reminded me of KO. I think If you really liked one of them you should give the other a try :)
