First of all The Casting of this drama was amazing, Ahn Bo hyun as the rich, spoilt yet kind brat was the best thing you’ll get to watch.
I know the story is very typical classic crime/action comic drama plot and I am sure like me everyone will have correctly guessed the main culprit at the very beginning of the drama but guess what its still an enjoyable drama.
When I was watching the second week I wasn't sure if the wanted to continue if the plot hadn't evolved. And yes, thankfully the plot and minor character developments were already visible.
And from 5th episode onwards, there was no turning back, the drama really covered very interesting criminal cases which made each ep exciting.
I was gonna give an 8.5 coz I think they could've done better in the 1st 4 eps BUT I'm giving this drama story a solid 9 just for how beautiful the character developments were.
Overall its a VERY typical kdrama plot but due to different cases covered and how mischievous Ahn Bohyun acted, this drama became really Refreshing.
