Everything said about this drama is true - lots of action, espionage, a quirky romance, and the best troop of compatible characters.
I would love to see a sequel with all the original cast. Do-Ha and Seol Woo have a kid (age 5-6) who's as sassy and confrontational as his mother and just as tech-savvy as his dad (McGyver type kid) and is constanly in trouble. Uncles Gwang and Dong-hyun are always there to bail the kid out. There is more to it, but that's enough of my fan rant; the bottom line is, I'd like to see a part 2.
The chemistry of the characters was evident, and if that's not true, then they did an even greater acting job.
Great job Kim Won-Seok
