You might be wondering why I am saying thus, let's start....

In general the show was a good one, with a good plot line but ended up missing the mark somehow. Lim sun was the best character followed by Ji ung right hand man( the investigator) and the rest, honestly Lee mi Jin kept on annoying me most of the time and I do not know why, I do not know is it the fact that she had studied for 7years but still was not curious enough to know why she got to change during the day and what would be the purpose until the last episodes of the show!!!!! a 7 for effort

STORY
The show had a solid plot not a unique one per say but could have done better. It was like two stories in one but felt disjointed somehow, they tried to weave them together but fell short, like her changing to the old ahjumma but still not knowing why she changed still baffles me and I have already finished the show, it made it so basic , i feel less episodes would be better and just finish up the story...
The whole missing case from 24 years ago and we still have no vague idea why it happened again, why the killer decided to kill again after 24 years then how lin sum and lee mi jin are connected to this. They could have stuck to one story line and flesh it out from there and find a way to fix the puzzles.

CAST
Lim sun was my favourite one , very funny that was a seasoned actress right there, If only her character had more depth. Then everything would have been great
Lee mi Jin was just annoying me for some odd reason I do not know if it was the script if it was the the storyline, but her character was a bore, she was good at crying scenes and being all sad and all but the fact that she had studied for 7 years, done various part times but she was never curious about anything like why she had changed how she fit in, what happened to her aunt especially now that she was working at the prosecutor's office.... Never solved anything.

The prosecutor, did a solid job stuck to his part but honestly never questioning the identity of Lee mi Jin until the 14/15 episode was a small disappointment from one of the best prosecutors, now the acting was great, subtle reactions and great screen presence

The other actors, the investigator, even the killer, the parents , the friend did an awesome job, they were able to support the cast in a way that made the show at least memorable to watch, funny moments and honestly some even outshone the main characters, like the killer loved her acting it was amazing...

The music, honestly i dont remember it, but i guess it was okay.
would I rewatch it? Not really , but I feel like the show would have been great if they had just connected the show well

so far so good you can watch it if you have nothing to watch would you be missing something great? yes maybe the comedy part but a solid 6.5 for me for this show...
