no spoilers here :)
this is a story of survival & anguish, and follows the themes in all the episode titles.
a father daughter(FL) duo 'sleuths' that finds missing people, including the ML 's mother, missing for 10years. the ML is an orphan who built a 'golden' empire with his shop & ressources. everything is set for a promising journey. and oh how it was!

I watched it as it was released, and the last episodes were released a few days later.

it's not perfect , but its memorable and left a huge mark on me, especially with the state of the world right now.
here are a few things i disliked:
the show felt like a stitch of many tropes, definitely sounding cliché at first but it gets a lot better!! I really appreciated the themes of the show ( usually displayed as their episode titles like chaos, despair, anguish etc)

some negative feedback:
- I never thought a ML could become more AND less shallow at the same time as the show progressed, but he does gain more depth.. so thats a relief
- not enough backstory or evolution of the enemy in the beginning, one has to be patient to get a deeper look there as its not given in the early episodes
- had some stranger things vibe with the sci fiction of the creature, but they sure added the kdrama touch !
- no spoiler but *some* elements don't add up or aren't explained. however its not a lot of things, most of the story holds well

some neutral feedback: i have the biggest deja-vu of the the Kako(Gato) character but i just can't seem to point my finger on it!!!! especially with experimentation & the glasses! i

some positive feedback
- the period style was superb!
-I loved all the characters and their evolution (almost)
- i loved the underground rebellious vibes (Especially the nuance within it)
- main story is very interesting and terrific
-loved the episode titles!! the themes were brillantly portrayed
-a light romance touch, i think it was perfectly balanced neither over/underdone
-the mother theme was deep yet barely put in our faces.
- also... BRILLANT SCRIPT!!! i looooved most of the dialogues especially between the power and the oppressed.

So-hee has come such a long way! been following her since nevertheless , and so much growth in her performances! she has a way of being subtle yet full of emotion & power!
i also am also very impressed with the whole cast! even the evil characters, young joon was so brillant in performing the disturbingly evil character! as well as su hyun!

IHAVE YET TO UNDERSTAND THE ENDING FULLY ( as it may be pointing for a s2, but thats not always a positive thing as they already had a big story in these episodes!)
things to watch out for: the first clue is in episode 7'th ending ( there was a long hiatus before the remaining episodes)
and the scenes in the last episode AFTER THE FIRST CREDITS!
the producers did put some clues but i am not sure about all of them!

brillant show!!!
