Channel A's 'Detectives' Trade Secrets' reveals the story of a man in his 50s who handed over 70 million won to his girlfriend, six years his senior, under the pretext of investment after she promised marriage, with suspicions raised of organized fraud.

▶ Girlfriend in Her 60s Who Promised Marriage Worked Unpaid for 5 Months Before Receiving 70 Million Won

The client introduced on the show is a 55-year-old man who first met his current girlfriend in February 2025 while having a meal with an acquaintance, and their relationship soon developed into a romantic one. Within about four months of meeting, the two promised to marry.

The girlfriend helped with the client's corn wholesale business, working alongside him from dawn to night for five months without pay. She reportedly introduced herself as a billionaire with assets worth 10 billion won and even mentioned plans to gift him a luxury foreign car.

The problem was money. The girlfriend encouraged the client to invest in cryptocurrency, claiming that a coin her son had invested in had risen from 1.5 million won to 150 million won. In the end, the client handed over 70 million won under the pretext of investment.

After the client's mother passed away in December 2025, the girlfriend personally did the grocery shopping and prepared ancestral rite food to take care of him, but the client said he fell ill during this period.
