Neoneun Idaero Daeun Jeokdo Eopsi

Five hundred years have passed since Mu-Jin began praying for the lost souls' ascension. Then, his lover, Geum-Ji, who died 300 years ago, appeared before him, reincarnated. However, she was already dead in this life. Unaware of her own death, she returned to Mu-Jin.
