everything is great, the plot twist, the actors, and the story plot. Even though I have many questions, but I recommend this drama. I'm still confused, why does the police catch "him" for murdering 11 person, but there are still 3 persons out of 11 reseter that's still alive. And also, the fact the woman and the old guy who asked a person to kill "that guy" before the reset, (and it succeeded) why would they even reset their lives. with "that guy" being dead at the beginning, those 11 persons are still alive, why would they even do a reset. To make their life better?

But I like this drama because it makes me think and the story is hard to guess. Not really hard, but you won't get a clue before the hints.
