Totally enjoyed this over the top spoof of a spy story.
The two leads play off each other well and the humour is fast and often slapstick. Not too be taken seriously, however, the fight scenes are very entertaining and despite a high body count it is not a gore fest.
The humour is not sophisticated and is often accompanied by a sight gag. I felt engaged and liked their characters.

The FL, Yoo Da Hee, played by Lee Sun Bin is suitably ernest and despite her small stature is quite fearless and brave. The ML, Woo Su Han played by Kim Young Kwang is, seemingly, naive and focussed on money but ends up with a surprising background that saves the story. I like this couples sparring remarks and later support and protection.

There is a Mission2: Possible in the offing so I will be waiting.....
