★ 4/10

Aside from the weak introduction, the first episode also had loads of exhibitions of the ML smarts through the typical genius character stereotype, however, the drama proceeded to treat the viewers like idiots for the remainder of the drama. Initially, Detective Cha Ji An, and most of the police force, were physically capable and adequate enough, however, they suddenly became as effective and incompetent as useless civilians. The mystery and thriller elements were generally bad, the drama didn't waste a second in revealing everything immediately. The romance was nothing but forced. The main story and entanglements of the brothers and the psycho man turned out to be disappointing and dumb, which led to a rubbish ending.

I enjoyed the mystery and the actors were great, but I didn't care for the storypart with the crazy old man in prison, so I skipped that most of the time. Other than that I had a good time and Seo In-Guk is always a good reason to tune in.
