The "F Girl" Phenomenon: Debut Controversy and P NATION's Bold Strategy

The debut of Baby DONT Cry was one of the most anticipated K-Pop events of 2025, not just because they are P NATION's first girl group, but also due to the immediate and intense controversy that surrounded their initial marketing.

The Deleted Teaser and Public Backlash

The group's debut single, "F Girl," was intended to be a bold statement about confidence and self-acceptance. However, the initial teaser video for the song ignited a significant controversy among netizens. The backlash centered on a scene that was interpreted by many to contain a controversial reference to a "condom," leading to widespread criticism about the appropriateness of the marketing for a rookie group, especially one with young members like Mia and Beni.

The controversy quickly escalated, resulting in P NATION taking swift action. The agency released a formal apology and deleted the offending teaser video, acknowledging the public's concern. This incident, while problematic, inadvertently thrust Baby DONT Cry and its members—Yihyun, Kumi, Mia, and Beni—into the global spotlight, making them one of the most talked-about debuts of the year.
