TDYA

TDYA was formed through Another Day of Debut Training, Studio USOG's variety show, in collaboration with South Korea's Ministry of Patriots and Veterans Affairs. The purpose of this group's formation was to perform at a music festival for South Korea's 80th Liberation Day. The group released their digital single "Keep The Light" on August 14, 2025 and performed the following day during the National Sovereignty Festival. Soon after, on September 5, 2025, the group completed their activities with the Another Day of Debut Training and disbanded after fulfilling their purpose.
