Joker007

First few episodes were heavy with familiar tropes like successful lead who gets married but loses everything & FL who is his wife wants to kill him because she thinks he killed her father, FL loves him & knows he can't be the murderer but still hurts him ends up poisoning him etc, but after they resolve their conflicts in record c drama time story starts to get better & better with each episode, interesting cases, good mystery, nice acting, good music, likeable Second leads no triangles etc. Just solving cases, it gets entertaining, it's not the best ever, but it managed to break away from the trope laden pit most c dramas fails to, usually for C dramas or any dramas first few episodes will be great then after that quality starts to decline, but for this drama story started in a way most will think it will be bad, but then it starts to improve with each episode.
Important characters don't break their characters unnaturally for story purposes.
Even I was biased with this drama but ended up enjoying it & managed to finish it, leads are married but don't expect heavy romance. Story centres around ML, but the main characters are together in all episodes for solving cases etc.
Reason for giving high ratings, mainly for breaking from tropes early on & not torturing viewers with extreme frustrating elements, plus good story, music, likeable main characters & supporting characters, important characters don't break their characters & start acting weird.
