Detectives: The Trade Secret: Shocking truth behind son-in-law's secret visitor

Channel A's 'Detectives: The Trade Secret' investigates the suspicious behavior of a son-in-law who brought a stranger into his home while his wife was away.

In the 'Case Notebook' segment of 'Detectives: The Trade Secret,' airing at 10 PM on the 7th, a mother's story is revealed as she suspects her son-in-law of entering a sham marriage to hide his true sexual orientation.

The client visited the newlyweds' home to check on her son-in-law while her daughter, married two years ago, was away on an overseas business trip. There, she witnessed an unexpected sight: a strange man sleeping in the couple's bed, dressed only in underwear. The flustered son-in-law explained that a close senior had drunk too much the previous day, so he let him stay over.

However, the fact that the two shared the same bed despite a separate guest room being available fueled the client's suspicion. Her doubts deepened after she personally witnessed the son-in-law and the senior hugging each other late at night.

The detectives' investigation uncovered further unsettling circumstances. The senior was observed visiting the house almost every day while the daughter was away, and the son-in-law even expressed his intention to live with the senior for the time being, claiming the senior could not match the move-in date for his new home.

The case took an even more unexpected turn when detectives observed the daughter, the son-in-law, and the senior having drinks together. After the son-in-law stepped away, the senior was caught attempting secret physical contact with the daughter. As the hidden truth between the three is finally revealed, the studio cast is left in shock.

Defconn expressed his anger, asking, "Does a person like this actually exist?" while Kim Poong reacted in horror, saying, "I need to go wash my ears." Daily detective Rhymer also expressed his disbelief, stating, "I want to meet that guy. I need to make him snap out of it..."

Joining as a guest detective for this broadcast is Rhymer, a friend of 25 years to Defconn. Having expanded his career from rapper to producer, he noted that he treats his artists like friends, revealing, "I even give dating advice to friends like Hanhae, Gree, and Muzie."

Rhymer, who has been running his company for 23 years, also shared his "eye for people" developed through long business experience. When asked if he can spot suspicious individuals at first glance, he mentioned his intuition, saying, "People whose eyes I thought were not good..."

The full story of the case, the twist hidden within the trio's relationship, and Rhymer's role as a detective will be revealed on Channel A's 'Detectives: The Trade Secret' on the 7th at 10 PM.
