Ferryman (2014)

Ferryman has similar themes - a mentor/supervisor from the underworld that's forced regular people to assist them in dealing with the dead - but it's not as goofy, though there's still humor. The Chosen Ones is the opposite side of the coin - a lot of goofy humor, and they're trying to prevent unnecessary deaths.

This is the original Ferryman. So far the plot is on the same trajectory. I recommend watching the first before the reboot.

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.

Both involve ghost-seeing leads assigned to work with the underworld to maintain order. Ferryman has 3 seasons + a movie.

The Ferryman series has a bit of the same vibe and came out around the same time, an unlikely group of people thrown together battling supernatural phenomena.
