My Roommate is a Detective is set in early 20th century Shanghai where the British and the local mob families rule the city. The story centers around a crime solving trio and similar to The Sleuth of Ming Dynasty, the central character is a genius detective who is sought after for his excellent observation, analytical and deduction skills. The central character loves food and money and prefers an easy going life (but is inevitably dragged into a bunch of cases). The bromance in the two dramas is amazing!
