'Secrets of Detectives' follows the suspicious behavior of a son-in-law who secretly invited a man into his home behind his daughter's back.
In the "Case File" segment of Channel A's 'Secrets of Detectives,' airing on the 7th in the afternoon, an urgent request from a woman is revealed: "My son-in-law may be hiding homosexual tendencies and has entered into a fake marriage with my daughter."
The client is a mother whose daughter married two years ago. While her daughter was away on a business trip overseas, she visited her daughter and son-in-law's home to take care of them, only to witness a shocking scene. A strange man wearing nothing but underwear was asleep in the couple's bed, while the son-in-law fidgeted nervously, as if he had been caught in a lie.
The son-in-law explained, "He's a close senior colleague who drank too much yesterday, so I told him to stay and sleep." However, the client could not shake off her unease over the fact that two grown men shared a bed despite having a guest room available. Eventually, she began to suspect that "whenever my daughter leaves home, he invites men over."
Shortly after, she directly witnessed the son-in-law and his senior colleague embracing affectionately in the middle of the night. Doubts about their relationship and the son-in-law's sexual orientation grew increasingly intense.

As the detective team launched a full-scale investigation, they captured footage of the son-in-law's senior colleague entering and leaving the house daily while the client's daughter was absent. Eventually, the son-in-law made a bombshell declaration: "I'm going to live with my senior." He claimed that since the move-in date for his senior's new apartment did not align, they would temporarily stay together in the couple's home.
The client's anxiety reached its peak as her son-in-law brought a man into their home under suspicious circumstances.

Later, the detective team observed the client's daughter, her husband (the son-in-law), and his senior colleague sharing a drinking session together. However, while the son-in-law briefly stepped away, the senior colleague attempted secret physical contact with the client's daughter, creating an eerie atmosphere.
Once the unimaginable truth hidden among the three was revealed, MC Defconn could not hide his anger, exclaiming, "Does someone like this really exist?" Meanwhile, Kim Pung expressed shock, saying, "I need to go wash my ears."
Rhymer, who joined as a one-day detective, shuddered and said, "I want to meet that guy. He needs to be shaken awake..." The episode airs at 10 p.m. on the 7th.
