As promised, this show certainly delivered many laughs. Yoo Hae-jin's character was put in so many fish-out-of-water situations, there was bound to be laughter.

Without a doubt, Yoo Hae-Jin is the star of the show and that was the biggest plus of the show for me. Without him, the show would probably have looked like a typical rom-com. YHJ played the assassin character with such gusto, enthusiasm, and earnestness, that I was absolutely won over by him by the halfway point of the show, despite his gruff outward appearance.

Lee Joon is good as usual. To be honest, even though his character had swapped lives with YHJ's character, his character development was quite different from that of YHJ's character, so it was not as enjoyable for me.

Jo Yoon-hee does an alright job as the kindly paramedic who gives him shelter and helps him to navigate through his new life.

Overall, a good watch for some light entertainment.
