casting was good but now that you said it, it wasnt really realistic and the actors probably could've had some…
I said 'Nah' because I disagree with your comment about the casting being good. The casting was not good at all. The casting was completely off. The roles given to the actors were not age appropriate and they looked like high school kids cosplaying as cops.
According to this article, apparently there is going to be a spinoff that is now officially in development with Cha Eun Woo as the male lead.
