Explanation for the Rewatch Value: rewatch value is 1 star because I don't usually rewatch dramas.

For me, this is the best drama I have ever watched. It's a complete package, it has suspense, thriller, comedy, tragedy, etc... No scene was wasted, I think, Everything had a purpose. The setup for the plot points, I think, all paid off in the end. I also want to appreciate the OST, besides the songs, the ambient music we hear during scenes were very good. It sometimes makes you think "Woah, why is the music like this? Is something going to happen or not?". I just want to appreciate the subtlety of it, because it greatly adds to the tension or suspense. The acting, I don't know what else to say, was phenomenal! Everyone did so well. Extra shout out to the antagonists, especially Eunseong. I hated him so much LOL.

The ending I think was perfect. They were still together, even after death. Atleast, that's what I thought it meant. The scene where the old Hyunwoo was visiting Haein's grave was extra special because of the scene where haein thought she saw an old man bringing flowers to a grave. Well, apparently it was hers. Such a nice callback to that earlier scene.

What a rollercoaster of a drama. It made my cry (many many times lol), laugh and sometimes at the edge of my seat. I'm kinda sad now that it's finished. I guess I'll go check out Soohyun and Jiwon's other dramas for now to comfort myself.
