I've been looking for another C-drama to watch, saw this was highly rated here on MDL and had a very interesting trailer that I've decided to watch this right away. I agree with a lot of the viewers here, that this drama was really good! I absolutely love the flow, the direction and writing for this series so much. I'll try to keep it spoiler free.

So before I go dabbling about the drama, for new viewers I think I need to address that there are issues that might trigger some.
TRIGGER WARNINGS: Sexual Harassment and Murder
BUT!!! They are not too explicit in the drama, though I just wanted to mention it for those that might get trigger on these. For the sexual harassment, it was just for a few minutes and was on moving closer and a touch (again not too explicit); but it did felt uncomfortable while watching the scene unfold. While for the murder part, the scene is censored in a way, the part becomes black and white, and the surrounding does become blurry.

Also the drama does have CN police propaganda. But despite the trigger warnings and the propaganda going on in this drama, I really hope that you all give it a try!

Things I love about this drama:
- For a time loop drama, majority of the time loops that happened does not feel repetitive (the only time it kind of does is when they found out who the suspect was, but it doesn't really bother me)
- The main leads! I love how both are smart, yet are a bit opposite of one another. The FL acts more impulsive on her emotions (which can sometimes be frustrating at times in the drama), but it's nice that the ML is more on the rational side. A nice touch seeing how they compliment one another; like how the ML will pull back the FL, as he wants to talk and plan things out before doing any actions.
- I love how the ML has a character development through the series.
- Each loop they go through, you get pieces of information and it was so well done. Even the build up to the next episode or loop was also great.
- This drama had me on the edge of my seat most of the time, and made me feel all kinds of emotions! I would suddenly be happy, sad, frustrated, relief and etc. Not a lot of dramas have actually made me feel a huge range of emotions like this.
- Can I say that all the casts' acting was so amazing! Especially the main leads, the captain and the suspect (especially the suspect, I love the acting so much!)
- Each passenger had a role especially towards the end of the drama, and I really love how most of the passengers' back stories were fleshed out. I have to commend that it was nice how their back stories made them feel more realistic and not just them being as extras in the bus.
- The drama touched several topics, and it's really nice seeing these topics get addressed out. Such as justice system, cyber-bullying, victim blaming and how most/some people would just standby to watch despite something troublesome is happening in front of them.
- How the burnt wounds looked so realistic.
- The drama is not too heavy.
- There's no voice dubbing on this drama.
- I know the drama can still be okay without the romance, but I love how it was just subtle until the final episode. There will be hints and all, but not too much to distract you.

Cons:
- There are several unanswered questions, but I think it's okay that they didn't directly answer these, because I feel if they were explained, it might just ruin the drama. So I'll based it on the theories I have read on.
- The suspect motives felt underwhelming. I was thinking the motives will be more darker and sinister, but apparently not. The motive is still valid, but I felt it shouldn't have been focused on the bus. But then again, the suspect was not in the right state of mind.
- There are times where you want to yank your hair out because of several characters' actions, and sometimes want to question 'Why?'. But then again, it reminds you that we're all human and if under pressure that we sometimes do questionable things as well.
- There are no back story for the main leads, to be honest it would have been a nice touch to introduce them and show their back stories like how they fleshed out several stories of the passenger. It's not much a con for me since it's understandable that this is only a 15 episode drama and the main point is breaking out of the time loop.

Overall:
This was just really a great drama. If I could just reset my mind so that I can watch this again for the first time I would. Hoping that more people get to watch this, as it was just so good. It's also very refreshing from the usual C-dramas I've watched, and hope that more C-dramas can be like this too. Though I think for re-watching, I would love to re-watch this after several years where I have forgotten majority of the details for this or want to relieve this drama.
