A case of a woman who invested 5 billion won in a woman she met in a department store VIP lounge, only to be defrauded, will be revealed on Channel A's 'Detectives' Trade Secrets.'

The victim is the only daughter of a company chairman known as a cash-rich figure in a major regional city. Although she was a department store VIP customer, she had been blacklisted for unpaid credit exceeding 100 million won. Amid this situation, she grew close to a woman. This woman, called her 'soulmate,' approached the client warmly, and the client built trust by gifting her a luxury bag worth 10 million won.

Then came word that the soulmate's husband ran a high-end dessert boutique in Gangnam and was expanding a premium brand business. Along with talk that private investors in business circles were waiting to invest, an offer followed to provide shares to early investors. Starting with a 1 billion won investment, the client repeatedly made additional investments under the names of expanding her stake and providing operating funds, investing a total of 5 billion won.

However, contact with the soulmate was cut off, and the company run by the husband turned out to be a paper company. Fearing her family would find out, the victim did not report the matter to the police and instead asked the detective team for help.

On this episode, global top model and TV personality Lee Hyun-yi appears as a one-day detective and shares her experiences with department store VIP events. Lee Hyun-yi mentioned glamorous products and accompanying bodyguards, saying, "A fur coat costs 80 million won per piece, and a necklace costs 1 billion won each." When Defconn expressed surprise upon hearing the conditions for being invited to department store VIP events, Lee Hyun-yi explained, "There's a big difference in sales between simple clothing displays and items worn by models."

Regarding the facts revealed during the detective team's tracking of the soulmate's whereabouts, Lee Hyun-yi reacted, "Good grief... it's breathtaking," and Defconn expressed shock, saying, "Yet another new type of villain has appeared." The investment fraud case and details about department store VIP rankings will air on Channel A's 'Detectives' Trade Secrets' on Monday, August 31 at 10 p.m.
