I'll save your time with this review of mine. Is this worth to watch? the answer is no.

I love Oh Hayoung (Yu Ha Ri) but the acting of hers and the other actors and actresses is not even mediocre. I find it cringey and makes me wince. The story is not even remarkable, using sci-fi to solve murder case is refreshing, but the way they portray and execute is meh. This drama has potential, the problem is, it just stayed as potential.

A 2.5/10. At this point just skip this and find another webdrama to watch.
