South Korea’s entertainment industry has recently been rocked by a flurry of controversy surrounding the acclaimed singer and producer MC Mong. Rumours have emerged suggesting that he was involved in an extramarital relationship with Cha Ga-won, CEO of the entertainment company One Hundred. Several Korean media outlets reported that Cha had allegedly showered MC Mong with lavish gifts, including substantial sums of money and luxury vehicles. In addition, private conversation records purportedly documenting the alleged affair were leaked online.
However, MC Mong has publicly refuted these claims. In an official statement, he categorically denied the allegations, asserting: “The reports circulating about me are entirely baseless. The leaked conversation records are fabricated, edited, and entirely manufactured from start to finish.” He further emphasised that his relationship with Cha Ga-won has always been strictly professional.
MC Mong co-founded One Hundred with Cha Ga-won in 2023. Earlier this year, in June 2025, he voluntarily stepped down from his position. Commenting on his departure, he said, “My decision to leave the company was driven solely by personal and professional considerations, with the aim of protecting our working relationship.”
One Hundred also issued an official response, denying any wrongdoing and confirming that an internal investigation revealed the leaked records had been edited. The company urged the public to refrain from spreading unfounded speculation and criticism, and hinted at potential legal action against those propagating false information.
Despite these clarifications, the controversy continues to dominate social media platforms and news outlets, sparking widespread debate about privacy, ethics, and the responsibilities of media reporting in South Korea’s high-profile entertainment sphere.
