It also aimed at the lifestyle of Ukrainian people. Unlike any standard reality shows, the series renowned for unique format of the use of interview; characters have presented to interview during post-scenes whereby the interviewer is unseen—often deemed orchestrated by the production crew.[13]

Bugrimova also maintains the casts' personal name employment depending on their personas while the remaining applied by using different persona names. The filming production began in August 2015.[7]

I think our viewers felt that the stories of the guys came to a logical end. There were a lot of comments: they say, what else? Well, what else could happen to these guys? We love all our heroes who have been with us all these four seasons. They managed to become related and become a family, to feel like parents of the guys. But, probably, in all families there comes a period when children need to be released into free swimming, so that they become better, reach new heights in their lives. The guys grew up and clearly understood what they want from life. And I really hope that at least a tiny percentage of this is the merit of Kiev Day and Night.[14]
