I started this drama out of recommendation. I don't know any actor/actress from this drama. All I know is this is a time travel drama, and it's very short, just 13 episodes. So worth a shot to watch it. Boy was I so impressed! In my opinion, this is the most well scripted time travel drama I have ever seen. The acting is fantastic, each actors having to act different versions of themselves, especially the male lead. For a Taiwan drama, this can be considered a very low budget drama as compared to those China or Korean dramas. But it's very well scripted, the scenes are well planned, the acting great. This is my 2nd drama review, and I hardly write any even after years of watching dramas. I hope Taiwan will continue coming up with more original gem like this drama. Thumbs up.
