The initial episode suffered from an uninspired beginning and relied heavily on familiar tropes involving exceptionally intelligent characters, yet it quickly devolved into a narrative that seemed to underestimate its audience. While Detective Cha Ji An and the police initially appeared competent, their abilities abruptly diminished, rendering them as ineffective as ordinary people. The suspenseful and mysterious aspects were poorly handled, with plot points being exposed right away. The romantic storyline felt contrived and unnatural. Ultimately, the central plot concerning the brothers and the dangerous individual proved to be underwhelming and foolish, culminating in a truly unsatisfactory resolution.
