Singer MC Mong, who recently resigned from his position as a producer at Big Planet Made Entertainment—a label under One Hundred—citing health reasons, has drawn attention by suddenly announcing that he will "expose all celebrities involved in illegal gambling."
MC Mong, who has been hosting live broadcasts on the video platform TikTok, claimed on his social media on the 18th, "I will hold a TikTok broadcast this evening at 8:00 PM, where I will invite reporters to discuss past events and everything related to me."
In particular, MC Mong explicitly mentioned individuals such as Mr. Cha, a construction businessman and relative of One Hundred Chairman Cha Ga-won, who is known to be a key source behind rumors of an affair between MC Mong and the Chairman. He warned of an online press conference, stating, "I intend to expose Chairman Cha, her group, and the celebrities associated with them."
MC Mong also piqued curiosity by mentioning MBC's "PD Note", a program reportedly investigating this matter, adding, "I intend to reveal everything about who they are colluding with and how they are conducting their investigation."
In December 2025, an online media outlet sparked controversy by releasing KakaoTalk messages alleging that MC Mong and Chairman Cha Ga-won had been involved in an affair for several years. In response, both MC Mong and Chairman Cha Ga-won stated that the reports were false and announced plans to file massive lawsuits for damages regarding the resulting financial losses.
