I found this drama unexpectedly while browsing YouTube. Even though I do not like the female lead actress at first, the storyline attracts me so I watch it. I wish for a better actress for female lead, but I found the actress likeable as I continue watching the drama. There is no annoying characters, no jealous love triangle, and no stupid misunderstanding between the main leads. It is not just only the main couple solving all the cases, outsmarting everyone else. All the characters have their own story, their own strength, and their own personality. The love story is not cheesy, and the whole drama is not sluggish. It is well written, well built, and well paced. Costumes are the only thing that shows this drama is a low budget one; the plot, the cast and the acting are no low quality. All in all, it is a drama well worthy of praises.
