one of those dramas that I wanted to watch an episode every day、but not all at once、 so as to draw out the enjoyment。 very suspenseful and with good tempo and movement between different strands of the story so no time to get bored〜however this was not a true sci-fi time travel drama more the idea of circular lives。 some aspects I dislike： the huge change in atmosphere between the next to last and final episodes I found strange and the ending is clever and intriguing but not totally satisfactory because it does not fit convincingly with the pretty definite ending to the previous episode； the relationship between ML and FLー I did not like his treatment of her or her taking it： I guess it is meant to be funny but for me verges on SM and falls flat： luckily for most of the drama the romance theme was in the background so did not affect the overall enjoyment I suppose they must have love interest to keep the audience ratings。still a very good drama〜 when K drama gets it right it is really good。
