Boy group ZEROBASEONE is set to kickstart its official activities with their debut on 'M Countdown'.

ZEROBASEONE (comprised of members Seong Hanbin, Kim Jiwoong, Jang Hao, Seok Matthew, Kim Taerae, Ricky, Kim Kyubin, Park Geonwook, Han Yujin) will appear on Mnet's 'M Countdown' airing at 6 PM on the 13th, performing their title track 'In Bloom' and the song 'New Kidz on the Block' from their debut album 'YOUTH IN THE SHADE,' released on the 10th.

The debut title track 'In Bloom' by ZEROBASEONE expresses their will to run towards 'you,' despite their incompleteness and immaturity, as they take their first steps that are all the more beautiful and meaningful due to their finiteness. The standout point choreography resembles spreading seeds, watering them, shaking their hands, and creating a fully bloomed flower, providing a sense of handing it over directly. The audience can feel the refreshing and energetic vibe of the nine members.

The song 'New Kidz on the Block,' also revealed along with the title track, embodies the nine members' ambitious passion towards the top. They've captured their determination to become the new kids who overturn the gray streets and head straight for the top, with a groovy bass, cheerful drum, and an easy and addictive melody that is hard to forget once heard. Both stages have been previously revealed through Mnet's 'ZEROBASEONE DEBUT SHOW: In Bloom,' receiving fervent attention from the global fandom.

Meanwhile, ZEROBASEONE has recorded more than 1.24 million sales in just one day with 'YOUTH IN THE SHADE,' making them the first K-POP group to achieve 'million seller' status with a debut album. Furthermore, all six songs included in the album, including the title track 'In Bloom,' entered the top ranks of major domestic music sites immediately after their release. In addition, 'In Bloom' ranked first in Japan's largest music site Line Music's real-time TOP 100, and a total of 4 songs including the title track entered 1-4th place on the Japanese music site AWA, achieving great success in both album and music streaming.
