Lee Sun Gyun and his wife, Jeon Hye Jin, may face monetary repercussions due to potential breaches in their advertising contracts. This predicament is a result of news spreading about Lee Sun Gyun's alleged involvement in illegal drug activities.

Kim Heon Sik, a pop culture critic and commentator, shed some light on the issue during a recent interview on YTN News. He stated, "The advertising industry is often the first to respond to situations like these. Continuing the ads could lead to substantial issues." He further added, "Lee Sun Gyun has been featured in numerous advertisements, often alongside his spouse. Even in the case of Yoo Ah In, the penalty fines related to advertising are so substantial that it is expected to be in the range of 10 billion KRW (7.4 million). It is likely that such consequences are explicitly outlined in their contracts."

The critic implied that the scandal is expected to impact Lee Sun Gyun's career significantly, stating, "Lee Sun Gyun is popular in the ad industry due to his commendable image. Consequently, the fallout from this situation will be massive and likely affect his future film roles."

News of Lee Sun Gyun and Jeon Hye Jin's predicament has raised concern amongst their fan base, with many users on online forums like Bobaedream expressing shock and worry. Some of the comments read, "I was really shocked," "The aftermath seems really significant," "I wonder if everything is okay between Lee Sun Gyun and Jeon Hye Jin," "Jeon Hye Jin must be worried," "Stay strong, Jeon Hye Jin," and "I hope things don't turn sour between Lee Sun Gyun and Jeon Hye Jin."

We're confirming the exact facts of the allegations currently being raised against actor Lee Sun Kyun, and we'll sincerely engage in investigations by the investigative agencies that may proceed in the future."

We will respond strongly if false information is spread due to malicious or false posts."

An official from the Incheon Metropolitan Police Agency's Drug Crime Investigation Team, which is investigating Lee Sun Gyun, stated in a conversation with Wikitree on the same day, "Currently, we are investigating a total of eight individuals, including Lee Sun Gyun."
