One of the greatest Korean movies I have ever seen. The plot is quite simple yet entertaining and the director/screenwriter (yes this movie was directed and screenwrote by one person, such a talented man!) did a great job at mixing we'll both the comedy and action scenes. The comedy ones were hilarious while the action and fighting ones were enough to keep me at the edge of my seat.
The main two characters had a great chemistry together although they were an unlikely duo. The female lead was more serious and the male lead more goofy but together they were contemplating each other very well.
I don't think there was anything that I disliked about the movie so if you want something funny and easy to watch while also being entertained and surprised by few of the plot twists, go watch this movie!
