This drama was sooooooooo interesting. I was completely hooked from Ep. 1 and my interest did not wane one bit till the very end.

The idea of a time loop has always faciniated me so watching this mystery drama was so fun! I loved the storyline and pacing of each episode. The decisions made by all the characters were understandable and reasonable so I was never frustrated with their decisions. Our main leads were brilliant, and always brought their A-game to getting down to the bottom of the mystery. So you'll never once feel like the characters are dumb or lack critical thinking skills. Everytime I had a thought/idea about the case, the characters would bring it up themselves and investigate/discuss it, so it felt like i was with them solving the case and their pacing always matched mine so I never felt frustrated at them for being slow or not doing more, which is a big issue in thriller/investigation dramas.

All the actors did a fantastic job. Not just the main leads but side characters as well, all the bus passengers, police officers etc. Every single actor felt natural.

Our main leads also had great chemistry. I wasn't expecting a romance plot to appear in this but I was pleasantly surprised and it absolutely made sense that both leads developed a romance. Although we only had a few moments seeing them be a couple, it brought a dose of sweetnesss to the show that was so very needed to calm you down from getting too worked up/tense from watching how the investigation plays out.

The music was also really good, the OST was very emotional and dramatic and the sound directing within the scenes was so well done too. They really made great use of music throughout the drama because it really heightened the scenes and made you feel even more tense/stressed/anxious as you are watching.

Overall, I had a fantastic time watching this. I was having a hard time understanding how everything would be resolved in the end but was completely satisfied with the route in which things went. It was all believable. So glad everyone got a happy ending as well!
In conclusion, I highly recommend.
