I saw this title coming across on my tiktok for some time and saved it in my 'plan to watch'.
When I finally started watching it, I didn't quite get the hype around it, that was until I watched episode 5.

The first 4 episodes are mainly backstory and didn't really captivate me, but after those episodes the 'revenge' arc started and I was immediately hooked.

It has 40 episodes in total and I might have almost watched 20 episodes in one sitting....
With most drama's, I get very bored towards the end because you can already fill in on what is going to happen because it is pretty cliche, I don't wanna say that The Double is not cliche, it kind of is, but the story is still very captivating, so much so that it left me very excited to watch the last episodes, which I can't say for most drama's.

Overall, I enjoyed this drama very much and I think it would be a perfect starter if you just got into cdrama's.
