Sung Si-kyung has reportedly suffered financial loss due to misconduct by his former manager.

His agency, SK Jaewon Co., stated on November 3, "It has been confirmed that Mr. A, during his employment, engaged in acts that violated the company's trust. He has since left the company."

The agency is currently assessing the extent of the damage and planning its response. "Our internal investigation revealed the seriousness of the matter. We are now verifying the precise scale of the losses," a representative explained.

They added, "We take full responsibility for insufficient supervision and are reinforcing our internal management systems to prevent similar cases. We sincerely apologize to the fans who love Sung Si-kyung for the concern this incident has caused."

Mr. A had been Sung Si-kyung's manager for nearly 20 years, overseeing concerts, broadcasts, advertising, and public relations. The two were reportedly as close as family.
