Synopsis (spoiler warning)

Bulgasal: Immortal Souls is a fantasy series about two people who are battling an ancient curse. Dan Hwal (Lee Jin-wook) was cursed at birth and changed into a Bulgasal, a.k.a. an immortal that thrives on human blood, while valiantly fighting monsters as a soldier, six hundred years ago. He’s now driven by vengeance in his quest to restore his soul. Meanwhile, Min Sang-Woon (Kwon Na Ra) is a former Bulgasal who has lost her immortality and is now living as a human in secret. When their paths cross, both of their lives will be altered.

8 Interesting facts about Bulgasal: Immortal Souls (contains spoilers)

(1) The term “Bulgasal” is derived from Korean folklore. Bulgasal, or “bu ke sha” in Mandarin, literally means “difficult to kill.” It derives from the Bulgasari tale, which tells the story of a terrifying monster who keeps expanding as it swallows all the metal during the late Goryeo period (918-1392).

(2) The plot spans 600 years and includes a variety of genres. The story begins in the present day, before traveling 600 years back in time to the late Goryeo period (my favourite). It tells the tale of Hwal’s ascension to immortality and the start of his difficult relationship with Sang-un.

Hwal has been cursed since birth and leads a terrible existence surrounded by locals who despise him. When a general adopts him and trains him to kill monsters, his life is forever changed.

Sang-un, on the other hand, is the owner of a soul that has a lot of terrible karma. She is pursued by Bulgasal and slaughtered by monsters in various life times, that have reincarnated as humans to seek revenge on her soul in all of her reincarnations. In her latest incarnation, she changes her identity and lives to get away from them after a horrible tragedy.
