Great sci-fi/thriller/mystery drama! The writing and acting are solid through all 15 episodes. It is a fast-paced and easy-to-follow story that develops all of the characters in a realistic and humane way. This made viewers grow an emotional attachment to the characters and feel for their story, which made me cry a couple of times. It made me want all of them to survive. None of the characters are dumb too, so it made it more fun to watch. There is also an unexpected humor aspect in some episodes which balances out the seriousness of the drama. The time loops aspect was written very smoothly and carried out nicely with the filming. The script did not fall apart and stayed consistent throughout. Each episode left you guessing, especially once you reached the halfway point. Also, each episode is meaningful to the storytelling and I did not notice any filler scenes at all. Not only that, there are subtle hints at the problems with society, such as sexual harassment victim-blaming.

The 15 episodes were just enough to tell the story and it had a great budget and cast, which shows that Chinese dramas can be so good if they only have a solid script and cast. And if dramas don't get too draggy with useless scenes. It's too bad China does not make more great dramas like this. Also, Bai Jing Ting's acting does not disappoint in this drama as expected. But this is my favorite Chinese drama of 2022 so far! I hope there will be more great dramas like this in the future. TOTALLY RECOMMEND THIS!
