I know Im can definitely pull it off but...

AWWWW, can you even imagine that sweet little face as a detective out for revenge???? I always have to remind myself that he is in fact in his late twenties.

P.S. Partner director? I know I'm reaching but it'd be hilarious if this was the screwball version of an undercover prison movie. Think of all the off colour jokes! Judging on the casting, probably not, but still.

"Inmate in a prison for revenge". Revenge seems to be all the rage in K-dramas these days. You've got Goodbye Mr Black etc. I'm just wondering how much this premise can truly play out; viewers are not inanimate and receive doses as the writer intends like the syringe theory suggests-we are individuals and say how many times can you have toffee with different wrapping in the same day. Please, (fictional) K-dramas gods allow some original ideas to trickle into K-movi.eland

the story seems quite dark and heavy to have a cute-faced actor like im shi wan. though i never judge a character based on the actor, sometimes their acting skill is just so great that you cant imagine someone else playing character. but i just wonder if they will use his face for the story's benefit because the plot somehow reminds me to a japanese comic where there is a pretty faced teenage boy who despite of his age they put him in adult prison which one of the boss notice that this boy have a profesional level assassin skill and the boy use his fragile looking n pretty face to trick people.
yeah, now i'm curious with the movie.
