Mizukawa will be appearing in the 3rd episode when she seeks refuge at the izakaya while being chased relentlessly by a tabloid reporter about a relationship rumour. She remarked that the atmosphere on the set and how welcoming everyone had been towards her made her feel at ease. Although this is the second time she is playing herself, there are parts which aren't related to her in real life. As such, there was some difficulty in saying those lines but she tried to convey them in the most natural way possible.
On the other hand, Shiina who will be appearing in the 5th episode, said that he first visited the izakaya 30 years ago when he just started out as an actor. As such, the lines given to him had a strong sense of reality and made him think back about his past which was incorporated into the script. In addition, being able to work with colleagues like Oomori and Yo who he knows well made him enjoy the experience very much. Coincidentally, this is also Shiina's second attempt at playing himself after he first did that in TV Tokyo Winter 2017 drama "Byplayers".
