Actress Go Min Si is facing allegations of school bullying, which her agency, Mystic Story, has strongly denied. A post was made online by an anonymous writer who claimed to be a former classmate of a well-known actress. The post detailed instances of alleged violent behavior, unethical actions, bullying, and extortion during middle school without explicitly naming the actress. Netizens speculated that the post referred to Go Min Si based on information like her former legal name, past photos, and an apology for underage drinking in 2020.

The allegations included claims of multiple classmates being bullied, money and belongings being extorted, verbal abuse, mockery of students with disabilities, and involving delinquent peers outside of school. The agency, Mystic Story, supports Go Min Si, dismissing the accusations as false. Go Min Si had previously admitted to and apologized for underage drinking in 2020, referring to it as a "careless mistake."

The writer of the post clarified that they were not seeking an apology or compensation but rather hoped the actress would cease her activities permanently to prevent any further harm.
