MBN's "Underpiptin" competed with 59 girls aged 8 to 15 and was embroiled in controversy over the commercialization and child abuse of minors.

Eight years old was included among the participants, and promotional photos with barcodes and exposed costumes raised criticism.

The Civilian Union and the Korean War Association called for the suspension of programs, establishment of standards for deliberation on broadcasting, and investigation of human rights conditions across the industry.

MBN said it is fully reviewing whether to air it or not, and the production team explained that it has been consulted with the consent of the guardian.

Civic groups emphasized the urgent need for institutional regulation of broadcast content for children.
