When i started out i did not have high expectations. How can they make a time loop concept intersting for 13 episodes i thought . But it's definitely interesting. It subverts expectations and breaks your previous belief about the characters. Each episode brought in some new knowledge that made me question the characters . Chemistry wise , the plot did not allow them to have a firey chemistry. But the subtle moments were conveyed wheel. ending was a bit confusing but overall incredibly satisfied with this show. One of the best this year to be honest. I really appreciate the writing in this. After this I'll try and find the original novel to read.
