I truly enjoyed every single episode. I loved the way they told the story, unveiling little by little and it really hooked me up, a lot. If you like crime/psuchological dramas you should watch it, don't even spend time reading reviews on here smh, GO WATCH IT! The only thing that didn't make me give it a 10/10 is one event near the end, which I found not really necessary buut nonetheless it was a fantastic drama. I still consider it as one of my favs (and I have only 2, including this one sksksk).
The characters are very well thought, just as their development through out the whole series (and I'm not talking only about the main leads). Every character had a presence and it really made the story flow smoothly.
The acting is on point, I was amazed by it because I did not expect that from a drama (I'm not saying the acting in other works is bad all the time, I just generally have low expectations but this one made me reconsider that).
Loved it, really.
