Abe revealed that when he took up the role, he thought it would be a good chance for him to speak freely since this is a love comedy involving adults. However, it turned out that his role is a person who becomes withdrawn into his own world due to stress from overwork so he remains silent most of the time. As such, in the first episode, the majority of his lines was just "iya". Nonetheless, he is still enjoying the filming despite being unable to speak as much as he wishes. When asked if he has any experience of feeling as if his heart had snapped, Abe said that if anyone is to tell him that he or she is going to watch "Dr. Rintaro" this season, he would be quite upset and so he vows to work hard to prevent that from happening. Dr. Rintaro is NTV's Spring 2015 offering in the same timeslot this season as "Kokoro ga Pokitto ne". On the other hand, Yamaguchi who plays Abe's ex-wife and Fujiki's current girlfriend, said that it is an exactly different story for her because she has a lot of lines to say in the drama so she's working very hard to memorise them.
