Watabe plays Sudou Tomozou, a 48-year-old lieutenant who used to be from the first investigation section and was taken off the frontline 6 months ago due to an injury and sent to the Ikimonogakari which takes care of pets left behind by suspects and those whose whereabouts are unknown. Much as he desires to go back to the frontline, he knows that his condition and age are not in his favour. Sudou meets the 22-year-old newbie police constable Usuki Keiko (Hashimoto) who graduated from the veterinary faculty in university and is a huge animal lover who prefers them to human beings. Sudou gets angry at how Keiko seemingly behaves without a care for others but gradually appreciates her knowledge about these animals and observant powers which help him in solving the cases they encounter.
As Yokoyama is well-known among children and mothers, Hashimoto revealed that whenever they are outdoors for location shooting, Yokoyama always gets surrounded by the children and their mothers which makes them so shocked at his popularity. Even though Yokoyama thought that he might not get recognised in his police officer uniform, he always gets identified easily by fans who take a second look at him just to make sure he is the real deal.
During the press conference, the cast members were joined by various animals which led Watabe to remark that he couldn't help but feel uneasy and worrisome although the filming process is enjoyable. As such, he hoped that this drama will become a signature work of his and pledged to work hard during the filming.
