The plot is very strong letting us to guess who is actually the mastermind till the end of series. Even after the mastermind is fixed as 'that person', they still make us doubt if it's really them. At the end it left us with the feeling of we should hate that person but he also has his own choice. It's grey. And I love that it makes me focus on the conversation or else I will miss some details.

The male lead character writing is very good. He has a strong mentality and smart thinking. Sharp in deduction and has a broad thinking with many back up plans. He is the best written character for actor Cheng Yi after Li Lianhua. His acting and action scene also very good.

The other characters are quite nice written especially the women characters. All of them are independent and strong in their own way. They are not the typically written weak, naive or need to be protected NO. They are AMAZING, COOL AND STRONG.

The OST is so good. I have been playing it on repeat. They only has 1 official song I guess but it's so good especially on bridge part. The melancholy feel in the song really fits the situation.

The camera shot surprisingly is good. There are some shots that were taken in one shot like a MV. It is cool. Also, the camera focus on one character is nice to look at. Some scenes also can be classic; the scene in archive room, the scene of Hongshen came down from stairs and the random shots of environment.

It's worth a rewatch 🫡.
