Since she is pregnant, her boyfriend named Jiwoo and a missing woman appear.
A woman with a 20-year-old college student daughter visits the detective team in Channel A 'Detectives' Trade Secret' casebook' which airs at 9:30 p.m. on the 30th. The client's daughter has never been upset since she was a child, and she was a sincere and exemplary student who passed a prestigious university without expensive tutoring. In addition, she was a good daughter who started living alone in Seoul at the same time as she entered university, and then worked part-time to earn tuition and pocket money.
However, at some point, the daughter, who had been worried about the lack of contact, comes home with her boyfriend three months later without notice. Then he delivers the news like a bolt out of the blue called '3 months of pregnancy'. The daughter's boyfriend kneels down to his knees and says he will be responsible for the client's daughter and the child in his stomach. However, the client demands that the child be erased, and a bitter conflict arises with the daughter who wants to give birth. Eventually, the daughter, who said she would go to the hospital at the client's earnest request, disappeared completely on the day of the appointment and went missing for five months.
After a while, the client follows the detective to the basement of a shabby villa. There, the daughter, who has been searching for so much, greets the client in a haggard look. But the strange thing was that I couldn't find traces of my daughter's boyfriend and child anywhere. And the story told by her daughter was shocking enough to overturn everyone's expectations. You can find out what happened to the daughter who left the house pregnant through the broadcast of 「Detectives' Trade Secrets」.
Meanwhile, in this broadcast, versatile actor Moon Hee-kyung, who has mastered dramas and musicals as well as hip-hop, will join as a daily detective. At the appearance of Moon Hee-kyung, Kim Poong exclaims, "'You're popular as a Korean Wave star these days.'" In response, Moon Hee-kyung provokes curiosity by saying "Director Shin Won-ho, thank you so much to writer Lee Woo-jung."
