During the open filming recently, Karasawa held a surprise birthday celebration by bringing a birthday cake and present for Kubota who turns 28 on 6 September. When asked what present he had got for Kubota, Karasawa grinned and said that it was a secret while Kubota commented that he will be looking forward to opening the present later. Karasawa added jokingly that it is a present which only men will know the meaning. Kubota expressed his appreciation for the celebration and will work hard in return for the kind gesture.
The drama describes how Karasawa's character Kyogoku Kosuke, a police detective during the Showa era who wakes up from his 30-year coma, teams up with his Heisei era colleague Mochizuki Ryota to solve cases. As it's been a long time since they met up, Kubota commented that it was not difficult to get back into the groove of things since the cast and crew are about the same as one year ago.
"episode 0" is a recap of how Kyogoku and Mochizuki became buddies and what had happened so far in addition to new revelations and a surprise announcement. Kubota commented that compared to when the drama was shown on Hulu, they will have to spend more time and energy on the filming this time so they will try their best to eat nutritious food and put up a good performance. Although the drama is heavy on the comedy aspect, the story's serious aspect is also highly valued so it is important to strike a balance between the two. In response to Kubota's comments, Karasawa praised him for being so good with words despite his young age and joked that he can't remember when he was first able to speak in such a comprehensive manner since he only thought about how to do his work.
