Basd on the very high rating, I expected a good drama, but I didn't expect it to be actually worth the high rating. Modern C-drama's don't usually excite me that much, but this one is really different.

The first 3 episodes are setting the scene. The problem, an explosion where everyone dies, is served and the main characters are introduced. The thrill and events really pick up from ep 4 and onwards. Every new episode, new problems and situations are presented and the issues get more and more complicated. Our 2 protagonists are dealing with getting everyone out alive, not dying in the process and not getting arrested and questioned because nobody will (and does) believe them.

Despite the many repeating situations (since they are in a time loop), the fact that there are some days they stay in the bus and others they try and succeed to venture outside makes it so it does not get boring. We are being fed clues and information to keep us engaged in the whodunnit part of the story, but we also get glimpses of the characters and lives of the people involved. Nobody is who they seemed to be in the beginning.

There is amazing pace, just enough action, plenty of suspense and even a little romance. This is a master class in how to make a modern fantasy/sci-fi drama.
