The characters performed well, but their character development and roles were lacking. It seems as if they were intentionally made to appear foolish.
The female lead frequently puts herself in perilous situations alone, almost as if she has a death wish. Naturally, she doesn't die because she's the main character, which is obvious. The storyline also focuses on her assisting an incompetent detective while neglecting her responsibilities at the veterinary hospital, as if she doesn't need to provide for her family.
The detective relies on the psychic abilities of others rather than seeking concrete evidence. He displays dominance over his colleagues and even his captain, yet fails to deliver results, making his character seem unintelligent.
The main lead witnesses the killer in action but fails to promptly inform the detective, allowing the killer to continue their spree. I can't comprehend how the staff managed to make this series so poorly executed.
