The cold swordsman and the warm warlock undergo a soul trial after death, uncover the secrets of the soul-devouring Gu and the ferryman, redeem each other in the memory copy, and finally join hands in rebirth.
Concept: caught between death and rebirth, obsession is both a shackle and a salvation. Only by facing your deepest inner demons and regrets can you cut off reincarnation and gain true liberation and new life.
