Seoul, South Korea – The entertainment industry is reeling from allegations of an affair between Cha Ga-won, CEO of One Hundred, and singer-producer MC Mong. Top Star News can exclusively report details of the alleged relationship based on leaked messenger conversations obtained by The Fact.

According to the report, Cha and MC Mong were not only business partners but also romantically involved. Their relationship reportedly ended in May, leading Cha to initiate legal proceedings against MC Mong for the repayment of significant loans. While the initial loan request was withdrawn in June, it was reinstated in November.

The exact timeline of their relationship remains unclear, but leaked conversations reveal that Cha reportedly transferred substantial amounts of money to MC Mong, including 30 million and 100 million won amounts. The total in 2022 was 4 billion KRW and continued into 2023.

The Fact published excerpts of heated exchanges between the pair from April and May, revealing intense emotional conflict. Messages suggest accusations of abandonment and broken trust. In one exchange, MC Mong says “The person you love the most, you abandon like a beggar and then say you were abandoned, like you.” Cha responds, “I never abandoned you. Live thinking that way.”

Further messages reveal discussions around attempting to conceive a child, with MC Mong citing stress-related fertility issues. He reportedly explained he was diagnosed with very low sperm motility.

CEO Cha Ga-won, who is married with children, co-founded One Hundred with MC Mong in 2023, serving as co-CEO. MC Mong departed from One Hundred in July and is currently preparing for a new album release.

The legal battle escalated recently, with Cha filing a 12 billion won lawsuit against MC Mong for the repayment of loans. MC Mong received a payment order and is expected to respond. The lawsuit and affair allegations have sent shockwaves through the entertainment community.
