At the press conference on November 15, Shin PD revealed, "Honestly, I had low expectations for Kang Seung Yoon. It's been awhile since I saw his acting in 'Highkick' and it's not like he continued acting since then. I forgot about him. I honestly didn't really know WINNER either. But I've heard they became popular with 'Really Really'. Then I met him and when he read the script with the dialect, the character came to life. That's why I cast him. There were no special benefits because he's an idol or from a big agency."
He added, "The same also applies for Krystal."
'Prison Playbook' is a dark comedy drama telling the story of a popular baseball player who becomes a criminal overnight. The first episode will be airing on November 22.
