Both dramas operate on the underlying theme of one male lead who sees ghosts and a second male lead who exorcises them.

Ferryman is somewhat like a darker, deeper version of Spiritpact in many ways - there are a lot of the same vibes and themes.

Ferryman is about a young man who has seen ghosts his entire life and ends up being recruited by a Grim Reaper for his skills. In a later season, he actually ends up in an official contract with the Reaper (Zhao Li) to catch ghosts before he can be given the opportunity to return to a mortal life.

Both films have a secondary female lead who is somewhat a romantic periphery interest but that romance theme is extremely subdued.
