I ended up having to rewatch the SP to recall the plot from there with relation to this series. Overall, have to say that this series was a nice follow up to the SP as the series delved deeper into the relationship between Tabito and Youko, as well as Tabito's dark past. That aside, as much as comedy was listed as one of the genres in the drama, I feel that it's more to a parody. As in, it's a parody of the mystery genre series as well as a parody of the Japanese lifestyle. Like how there's a kink cafe with themes of injured women, a pair of police duo with an eccentric partner, a perverted old yakuza doctor as well as parodies of a lot of detectives and yakuza tropes in general.

That said, I have to say that the drama plot was quite balanced. And I love how a lot of things regarding Tabito's curiosities towards Youko, the relationships of the people from the detective agencies as well as Tabito's dark secrets were written in a way that was natural and not forceful. Like as much as some might argue that the focus on Tabito and Youko's relationship was unnecessary, Youko's presence was essential in the drama. As hinted by the yakuza doctor from the SP, surely enough Youko's influence was key towards Tabito's recovery to regaining the rest of his senses. Also, the very fact that in every episode there were subtle hints about Tabito's past alongside the other cases provide reasons as to why you would want to rewatch the series from the beginning to pick up all of the subtle hints.

All in all, as much as a lot of the elements in the drama was written in a parody-like setting, it's still an enjoyable watch for people who love mystery/detective genres dramas in a not so serious way.
