[My Daily – Reporter Park Rosa] An investigation is underway into suspicions of infidelity involving a married woman who abruptly requested a divorce and a young swimming instructor.
The upcoming episode of Channel A’s Detectives’ Trade Secrets (“??”), airing at 9:30 p.m. on Monday, features the story of a man who approached the detective team after his wife suddenly demanded a divorce. The client, who runs a restaurant, reportedly told the detectives that his wife, who often helps at the restaurant during lunchtime, had recently begun wearing perfume and would show up with wet hair, raising his suspicions. He also claimed that CCTV footage captured her stealing money from the restaurant, reinforcing his belief that she was having an affair.

According to the investigation, the wife headed to a swimming pool shortly after her husband left for work. There, she was observed interacting affectionately with a young and attractive instructor during her lessons. Rumors circulated within the facility suggesting that she preferred younger men, and that a young man was often seen waiting for her outside. Before long, investigators caught footage of an unidentified man actually waiting for her at the pool’s entrance.
Contrary to the husband’s expectations, the man was later seen demanding large sums of money from the woman and threatening her. The detectives also discovered that he frequently met multiple middle-aged women each day, apparently extorting money from them. Defconn suspected that the man might be working at a host bar, while Lee Sedol expressed disbelief, questioning what kind of person would exploit women in that way. The man’s true identity—and the shocking nature of his relationship with the client’s wife—will be revealed in the broadcast of Detectives’ Trade Secrets.

The episode also features Go legend Lee Sedol, who joins the show as a guest detective, displaying his witty sense of humor. Despite having earned more than 8 billion KRW (approximately 5.6 million USD) in prize money, the program highlights his unexpectedly frugal lifestyle. When teased by Defconn about always wearing the same clothes and possibly cutting his own hair, Lee reportedly responded humorously that his thrifty habits matched his name, as “dol” means “stone” in Korean. The episode will further explore what Lee—who claims to have little material desire—considers his greatest personal indulgence.
