Story: At first I love the intesity of this drama, like you can't take your eyes off from every scene. But I think the story start to get messy after that 10 years later. I see how the writer do not care at all about the consistency of the character, and some scene just do not make any sense, especially towards the end. I think the writer only care about the tension and twist after twist. Too much twist also not good tbh.

Cinematography&Video Editing: I have no comment with the cinematography but their editing was so lackingly noticeable, how they cut the scene and move to another angle, also the billboard news scene like idk if you guys notice but I can't really explain with words.

OST: Tbh all the ost was good! I do have few song that I added to my playlist so I don't have anything to say about OST

Acting: The reason why I stay watch this drama until the end was the acting of the cast. Especially Sungjae... I watch him since School 2015, Goblin, Mystic Pop-up Bar and I would say his acting was the best in this drama. The emotion, facial expression, his narration and tone was really good! Chaeyeon also good this is my first time watching her acting and she will do good in the future
But overall the acting was superb, also Choi Wonyoung as villain seriously giving me a goosebumps, indeed I can trust him with any role

Ending: The ending not satisfying but I'm okay with that

The conclusion I don't think I want to watch any work from this writer of the drama but looking forward to all the actors next project
