Last week, it came to light that the Drug Crime Investigation Unit of the Incheon Metropolitan Police is currently probing eight individuals under suspicion of illegal drug use at an adult entertainment venue in Gangnam.

The individuals reportedly under investigation include renowned actor Lee Sun Gyun, known for his roles in 'Parasite' and 'My Mister'; Hwang Hana, the granddaughter of 'Namyang Dairy' founder Hong Doo Young; and ex-idol trainee Han Seo Hee, previously indicted three times for drug misdemeanors, including one in 2016 involving former Big Bang member T.O.P.

Most recently, on October 23, Dispatch disclosed that the anonymous informant who first mentioned Lee Sun Gyun's name is allegedly a manager of 'Tenpro,' a well-known Gangnam adult entertainment establishment.

The informant's assertions suggested that Lee Sun Gyun had been a VIP guest at Tenpro and was suspected of drug involvement. Due to these latest allegations, the spotlight has since turned to Han Seo Hee's association with Tenpro.

In a related case in April of the previous year, the Criminal 6-3 Division of the Seoul High Court held the first appeal trial for Yang Hyun Suk, the founder of YG Entertainment, who was indicted for special crime penalty violations. During the trial, Yang Hyun Suk recollected meeting Han Seo Hee in August 2016 at Tenpro, stating, "Han Seo Hee and I had a conversation for about 20 minutes at YG Entertainment, and I assumed we could comfortably interact again as we were acquainted through Tenpro."

Han Seo Hee confirmed this during the trial, confessing to working at Tenpro and explaining her introduction to Yang Hyun Suk, "I came to know Yang Hyun Suk through the recommendation of a Tenpro madam. After just sitting there for three hours, I was given 2 million KRW (1,500 USD). I was tempted by the money and subsequently agreed to work there."

These revelations have sparked speculation surrounding Lee Sun Gyun's involvement with Tenpro and individuals like Han Seo Hee. With the latest information given, many speculate all the individuals named are connected to the drug case.

Lee Sun Gyun's legal counsel refuted the claims during an interview with Yonhap News on October 23, affirming, "He denies all knowledge of and association with the granddaughter of the conglomerate family or a former idol aspirant."
