I was so shocked to learn that Min Sang-Un is not really the one who murdered Hwal's entire family 600 years ago. I hope Hwal's cold actions towards Sang-Un disappear. I understand his pain of losing his family. I understand how guilty he was for not saving his wife, Dan Sol and his i, A-chan. I also get why he wants his soul (that was taken from him) back desperately and become a human again even though he was aware that there were monsters (the reincarnated monsters that he killed 600 years ago, those monsters were reincarnated as humans) that are after his soul. His plan when he regain his soul is to die to escape the pain and guiltiness he has for 600 years because of the past Min Sang-Un (Min Sang-Un turned Hwal a bulgasal ang stole his soul, but she didn't kill his family, it was Ok Eul-Tae, another Bulgasal who wants to kill Min Sang-Un for the curse she has given to him which is the dark hole in his chest). He also plans on turning Min Sang-Un a Bulgasal again for her to feel the same pain he felt for 600 years and to lock her up into the well he made 600 years ago.
In episode 7, Gapsangoe tried to kill Sang-Un and when Sang-Un starts to choke, Ok Eul-Tae starts to choke too. So my theory about that is that Ok Eul Tae ang Min Sang-Un shared a same soul that's why whenever Ok Eul-Tae attempts to kill Min Sang-Un, black blood starts to come out from his dark hole. Eul Tae said that Sang-Un's twin sister (Sang-Yeon) did something. It was also revealed that Ok Eul-Tae is the who killed Sang-un's family too. Sang-Yeon does remembered everything that happened in the past while Sang-Un didn't. Sang-Un was reincarnated with twins so Hwal's soul was split into two. And.... Do Yoon, the high school student whom Hwal let to live in his house was actually a spy of Eul-Tae.
Watch this drama please!! So worth it! Everything makes sense. So many plot twists! 😍 Love this drama so much. And also hope that there will be a romance between Hwal and Sang-Un! Can't wait for episode 9!!!! 😭😍❤️
