This movie is extremely hilarious! There were scenes which I seriously can't get over with and had to replay a couple of times. The two mains' chemistry was surprisingly good and their characters are well-matched. I find the actress' voice really funny and Lee Dong Wook actually pulled off the action parts quite well. Although a lot of scenes were forcibly coincidences, you'll let it off since it is really compensated by fun and great acting. This movie is what you call comedy!
