The anime has an interesting idea but not very entertaining it is mostly just sitting at a table in one room and talking. There isn't really any mystery or at least one worthy of getting interested in. These 'mysteries' wouldn't exist if the parties involved just talked to each other, especially in ep 3.
The story and art aren't bad but nothing to write home about either. Sound is kind of not really something that is really focused on here.
The characters are kind of boring Richard is bland and uninteresting, Seigi has his moments and is probably only a bit more interesting than Richard at least.
welp it is mostly just these 2 plus their clients sitting in a room and talking. That's it. It isn't really something I think people would enjoy
