No speculation. No exaggeration. Just the facts – explained in plain.

Who Is MC Mong?
MC Mong is a well-known figure in Korean music. He debuted in 1998 as part of the hip-hop group People Crew and later built a successful solo career after 2004. His music topped charts, and his variety show appearances made him a household name.
His career faced a major setback in 2010 when he was accused of evading mandatory military service. After a long legal process, South Korea’s Supreme Court acquitted him in 2012. Since then, MC Mong has largely stayed behind the scenes, working as a producer and executive rather than a front-facing celebrity.
In July 2023, he co-founded the entertainment company 100th Entertainment (Won Hundred) and became involved as an executive producer under its subsidiary, Big Planet Made Entertainment.
Who Is Cha Ga-won?
Cha Ga-won is the chairman of Won Hundred, the parent company of 100th Entertainment. She is a business figure rather than a public entertainer, which makes the situation more sensitive.
Her name entered public discussion only after reports linked her to MC Mong through alleged personal and financial ties. According to media descriptions, Cha Ga-won is married, a detail that intensified public reaction when the allegations surfaced.
How the Controversy Started
The controversy began on December 24, 2025, after a report published by a Korean media outlet sparked widespread attention across the entertainment industry. The report was later referenced by multiple Korean news organizations.
According to the report, the following allegations were made:
- MC Mong and Cha Ga-won were involved in an inappropriate relationship for several years
- Cha Ga-won allegedly transferred approximately 12 billion won to MC Mong
- The money was claimed to be linked to their personal relationship, not professional dealings
- After the relationship reportedly ended, a lawsuit was filed to recover the funds
- The report also mentioned expensive gifts and alleged KakaoTalk messages, suggesting interactions beyond professional boundaries
As soon as the report was released, the story spread rapidly on social media. Public opinion formed quickly, even before official responses or verified evidence became available.
These allegations were later summarized and reported by established outlets such as Korea JoongAng Daily, which clearly noted that the claims were disputed and denied by those involved.

Immediate Response From 100th Entertainment
On the same day the report surfaced, MC Mong’s agency, 100th Entertainment, released a strong official statement denying all allegations.
According to the agency:
- The report contained false information
- The KakaoTalk messages cited were fabricated
- Claims of an inappropriate relationship were completely untrue
- The company would pursue strict legal action against those spreading false information
The agency also emphasized that it had internally verified the facts before releasing the statement, a point that holds particular importance in potential legal proceedings.
This official response was later covered by multiple Korean entertainment news outlets.

The KakaoTalk Message Dispute
One of the most serious elements of the controversy centers on the alleged KakaoTalk messages, which were presented as evidence of a personal relationship.
According to 100th Entertainment:
- The messages were not authentic
- They were created during a period when MC Mong was under significant pressure
- A relative of Cha Ga-won allegedly threatened MC Mong during an internal dispute
The agency stated that the real conflict was related to management rights at Big Planet Made Entertainment, not a personal or romantic relationship. They claim the messages were later leaked or shared with the media, leading to misleading reports.
If it is proven that the digital evidence was fabricated or manipulated, it could significantly change the direction of the case.

MC Mong’s Personal Statement: What He Said and Where
MC Mong also addressed the allegations personally through a post on his official social media account, which was later deleted.
In his statement, MC Mong said:
- He never had an inappropriate relationship with Cha Ga-won
- The 12 billion won was related to a debt repayment issue, not an affair
- The KakaoTalk messages were either taken out of context or rewritten
- Some media outlets combined unrelated messages to create a misleading narrative
Although the post was later removed, this does not invalidate the denial. In high-profile legal situations, public figures often delete statements after consulting with legal counsel.
MC Mong’s statement was quoted and reported by several entertainment news outlets.

The 12 Billion Won Question Explained
The figure of 12 billion won attracted immediate attention. It is a large amount, even by entertainment industry standards.
According to reports:
- Cha Ga-won filed a lawsuit requesting repayment
- MC Mong did not object within the legal timeframe
- The court finalized a payment order
MC Mong clarified that this amount represented debt, not money given due to a personal relationship. Debt disputes between business partners are common, especially when companies dissolve or leadership changes.
While the number sounds dramatic, money disputes alone do not prove personal misconduct.
Legal Action and Zero-Tolerance Policy
100th Entertainment confirmed plans to pursue strong legal action against:
- Individuals involved in spreading false claims
- The media outlet that first reported the story
The company stated it would adopt a zero-tolerance policy toward defamation and malicious rumors. This language is standard in Korean entertainment disputes, but it signals confidence in their legal position.
In South Korea, defamation laws are strict. Publishing false information can result in criminal and civil penalties.
MC Mong’s Exit From Won Hundred
Earlier in July 2025, MC Mong left Won Hundred, stating that he planned to study abroad for health and personal development.
At the time, the announcement raised a few eyebrows. In hindsight, some observers now question whether internal conflicts influenced his departure.
However, no official documents or statements connect his exit directly to the current controversy. Any such claim would remain speculative.
Industry Context: Why These Stories Escalate Fast
Korean entertainment scandals follow a predictable pattern:
- A media outlet publishes an exclusive
- Social media amplifies the claim
- Agencies release denials
- Legal teams enter the picture
The MC Mong– Cha Ga-won controversy fits this pattern perfectly. Once money and private messages enter the discussion, public opinion often forms before facts are confirmed.
This is why verified statements and legal outcomes matter more than online reactions.
What Trusted Sources Say
Major Korean news agencies such as Yonhap News, The Fact, and official company releases provide the core information used in this case.
No international agency or court ruling has confirmed the affair allegations as of now. That distinction is critical.
Until legal proceedings conclude, the controversy remains allegations versus denials, not established truth.
Why Caution Matters for Readers
It is easy to treat celebrity controversies as entertainment. However, false accusations can cause permanent damage.
This case involves:
- Private individuals
- Corporate disputes
- Alleged fabricated evidence
- Significant financial claims
Jumping to conclusions helps no one– not fans, not media outlets, and certainly not the truth.
