It is a lighter hearted spy thriller with lots of camaraderie and fun. It is hilarious watching how a network of ahjummas can beat the spies at their game. There's a little romance thrown in but the story is much more about the love in the community and how they all support each other. Son Ji Sub is his always very cool self but absolutely enchanting interacting with the Joon- Joon twins who he babysits as a cover. Highly recommended as an entertaining series.
