Akai Nurse Call

Both are really good thriller-comedies and share the same vibe. Both even have the perfect amount of mystery involved.

The ML is admitted to a hospital after facing an accident while this hospital has mysterious deaths surrounded (there's a serial killer) while he want to protect his fiancee who is also admitted to this hospital just like how the ML in Gannibal also assigned to this village full of cannibals where he has to protect his family and solve the mystery.

Same as Koi wa Yami, the drama is also led by a couple. This couple was caught with a series of serial killings which will prompt the two to investigate about who is the culprit behind these incidents.

Both shows have very similar atmospheres. Creepy and mysterious with a touch of humor. Both also share the theme of creepy neighbours (the neighbours in the apartment in rose mansion and the fellow patients and staff at the hospital in ANC)
