Rising K-Pop Girl Group UDTT Officially Debuts with ‘School Rush’ and ‘Really Really’

A new force is emerging in the K-pop scene as rookie girl group UDTT (WooDangTangTang Girls) has officially launched their debut. Comprising members Risako, Han Chae-hee, Koo Hanna, and Kwon Ye-jin—familiar faces from survival shows like Girls Planet 999: The Girls Saga (Mnet), Universe Ticket (SBS), and After School Excitement (MBC)—the group released their debut single ‘School Rush’ on June 29.

The title track ‘Really Really’ is a deep house-based pop song featuring a catchy melody, poetic lyrics, and youthful energy that captures the fluttering excitement of first love through UDTT’s universal charm. The debut showcases the talents of globally acclaimed producers Kim Joo-hyung (of ENHYPEN, IVE, STRAY KIDS fame) and Hayley Aitken (known for work with TWICE, ITZY, NiziU, (G)I-DLE, and Red Velvet).

UDTT is the flagship girl group from ttMusic, a global record label making its presence known with the group’s exciting concept and polished presentation.

In addition to their music, UDTT is promoting with a high-concept ‘High School Special Track’ storyline that teases mysterious new developments, including a soon-to-reveal fifth member. A teaser hinted at the addition of an international student, who is expected to make her debut alongside the group during their first performance on SBS MTV’s ‘The Show’.

UDTT’s momentous journey is just beginning, and with tracks like ‘Really Really’ and the previously pre-released ‘Retry’, their debut single sets the stage for a dynamic entrance into the world of K-pop. Their agency commented, “UDTT is a global girl group made up of members who have already proven their talent, visuals, and potential through various audition survival programs. We look forward to fans around the world joining them on this thrilling ride.”

The group plans extensive promotions across music broadcasts and digital platforms as their fresh energy begins to ripple across the K-pop universe.
