Hamano plays the lead character Itsuki Misao while his late wife Junko will be played by Kurashina Kana. His only daughter Aware will be played by Awano Sari and their neighbour Manda will be played by Kawaei Rina. Adachi Yumi will play the boss of the agency which manages Misao. Co-stars also include Sato Ryuta.
Hamano commented that he is very humbled about being given the chance to play the lead character even though he doesn't look like leading man material. However, he will try his best to play this character in this wonderful story and hopes to convey the happiness which many fellow musicians experience as they begin their careers.
The theme song "Otoko no Misao" will be featured as an insert song in the drama. The lyrics are written by Gouda while the melody is composed by Tsunku who was asked to do so at the request of Gouda. Tsunku commented that he used to immerse himself fully into the world of singing before he made his professional debut so he could identify with the theme of the story. He said that he was honoured to be selected to write the melody and is confident that the song will be a perfect match for the drama especially since Hamano himself is a musician in a band.
