Ahhh !!! Lovely !!! At last a writer thought of sending an forensic expert instead of doctor to the past .. otherwise I didn't even remember how many present- past travel series I watched almost all of them were about a person who is apparently doctor/medical expert by profession ...
The storyline was very interesting and to the point as she travels to past, she right away starts using her expertise as forensic expert to solve cases .. like no beating around the bush ... Meanwhile she also is remembering these visuals that are related to her tragic present situation making the plot running simultaneously in present and past ... ( Won't give more spoilers you check out for yourself)

At last I will say for many series which dont actually have good writing but still a huge viewership , I think this one is quite Underrated .. i feel it literally takes a good amount of brain power to write such stories especially in short drama format.the writer need to be appreciated for the hard work.

Coming on to the cast both FL and ML did great job ... FL was a perfect pick for the character she is acting shades of her character so effortlessly.. her emotions goes 'on to off' as soon as she starts her investigation with the corpse with that peculiar way of dialogue delivery .. just amazing.
ML seems to be a new actor haven't seen him before this but he did a good job as well .. he was able to deliver the best in both of his characters.

Overall a good show .. 👍
