First episode got me hooked. I almost gave up 2019 because there was barely anything that kept me intrigued, but I thought with Camellia and this that things were going better!
I liked the fillers with the case after case format, and the fact that they successful blended thriller and romance. The slow burn made it evenly distributed through the drama and you don't have the impression of watching 2 different series.
The concept for the killer wasn't that unique tho, but it could've worked very well. The interesting part was how the killer planned the grasshopper thing to make himself an alibi. It's just that the pace was odd (they revealed those too early imo) and some tiny holes kept bothering me at a point I really couldn't ignore them like: how did the killer traced back all his victims? I mean his plan was to rob their wallet to lure them in dark places (and who sane in their mind would just enter those tbh) but how did he knew where to strike? What the metro police did those 2 years? They investigated...what? Both side leads where kinda unnecessary...the girl was just bitching because no one believed in her (tho I think the male lead was a dick not to tell her the reason to break up. Is this noble idiocy in reverse? Lol) while she was unprofessional and she put her personal feelings into the investigation (and seriously, 3 episodes on that damn telephone booth), the male side cop was intriguing at first...it was purposely suspicious but then he became just the trigger for the ml jealousy...meh. I thought that maybe he too had lost someone because of the ghost, but unfortunately they didn't delve into his character.
Also those are the worst cop and criminals I've seen in all my life. Cops that let criminals that they've been chasing for 3 years escape so easily (actually it even happened offscreen lol), criminals that keep their phones while on the run, fingerprints on cigarettes, coins and wallets. Like seriously those are legendary thiefs? XD
Female lead was annoying but I accepted that in her pov cops are untrustworthy (but why she couldn't judt trust the ml remained a mystery as why they go on night duty to sleep and how the ml lived after selling his house) and she was blinded by her sister's death (presumed lol) .
But usually autistic people are followed by professionals, they said she was taking care of her ALONE by the age of 10 and that's absolutely impossible xD
Overall wasn't that bad, but I was so excited at first that my expectations skyrocketed and I felt hard the disappointment twt I had a lot of theories, involving people like the nurse friend, the caretaker, the mysterious lady with red shoes, the other cops, that mystical door with the abandoned project of another line and it was very simpler than what I imagined xD
