By "on edge" I mean that this series literally leaves you on the edge of your seat after every episode. Lee Joon-Gi (Baek Hee-sung) was so perfect for the lead role. He is such an amazing actor and I never imagined him being able to pull off such an intense and bad-ass role. But he did it!!! An emotionless character who falls for a cop... could it get any better than that!!! And the times where he almost gets caught but gets away with it... it honestly gives you such an adrenalin rush every time!!!! Moon Chae-won (Cha Ji-won) was such a good choice for the lead actress as well. I've seen her in other dramas but this was honestly my favourtie series that she featured in.

Honestly, give this series a go!!! I promise you, that you won't have any regrets!!!!
