What is the Korean drama Ghosts about?

Ghosts, whose full name is Lonely and Brilliant God: Ghosts, was a fantasy love Korean drama last year. It was very popular when it was broadcast, and I have been following it.

This drama is about the wonderful cohabitation of a ghost who wants to end immortal life, a messenger from the underworld who has lost her memory and a girl who calls herself "ghost bride".

Kim Shu, a general in the Koryo period, was killed because of the suspicion of the king. After his death, he gained cursed abilities-"eternal life" and powerful abilities. Jin Shu, a "ghost" with immortality, had to find a human bride in order to end her endless cycle of life, but she started a wonderful "cohabitation" life with Wang Li, the messenger of the underworld who lost her memory on the way. After they met the legendary "ghost bride"-a girl who was destined to die, the romantic and fantastic story began. This TV series with novel theme, creative plot, stable plot rhythm, strong production team and star performance lineup is definitely worth watching.
