This show is sooo underrated. IMHO this is one of the best dramas I have ever seen. Great story, great direction, great acting, everything is great. The episodes are short, makes it an easy watch for me. This is a "must see drama" for those who love crime and mystery thriller. Hoping for a part 2 I'm not used to writing reviews but since this landed on my favorite lists, thought what I have initially written deserves an edit. Why am I sooo in love with this drama???? 1. I love how the story was presented in such a way that it stimulates thinking and imagination. Each episode keeps me on my toes and are full of surprises. 2. Unlike other dramas that has a lot of repetitive scenes obviously to make the story longer, all the flashback scenes in this drama are necessary and important piece of the puzzle 3. I love how each episode are presented in such way that there seems to be an end like the Kdrama "Signal" but are still bits and pieces of a big puzzle. Well written indeed 4. The drama is not cheaply done, I am treated to a movie-like production with great acting, direction and cinematography 5. Lastly love how the drama ends makes me crave for a part 2
