Mondai Bukken

Both dramas blend the supernatural element with very human motives for crime.
Both dramas have a very charismatic ML mentoring the younger, inexperienced FL.

Some similarities:
- drama about solving bizarre real estate property cases that give haunted house vibes
- episodic format (a new case every episode), while a bit of the main story continues each time and we learn more and more about the characters in the process
- no romance, but lots of shipping potential
- found family and teamwork
- supernatural elements
- comedy

Some differences:
- the cases in Peaceful Property have supernatural origins
- the cases in Mondai Bukken only appear to be supernatural, but can be explained logically
