Yeonnam-dong 539 sounds like an interesting slice-of-life, omnibus type of show, where the focus in each episode will shift between different housemates who all live in the same sharehouse. Lee Jong-hyuk's character is a detective on the cyber investigations team who specializes in voice phishing. Unlike most detectives we come across in dramaland, though, he sounds like a big ol' teddy bear inside and out, with endless sympathy for the underdogs of society and a strong sense of responsibility, while also being more soft-hearted than most.
