ZEROBASEONE

ZEROBASEONE (ZB1) is a South Korean boy group formed on Mnet's show Boys Planet and managed by WAKEONE. They debuted on July 10, 2023 with the mini album Youth in the Shade and the song “In Bloom”. Formed with nine members, the group has continued as five since 2026: Kim Jiwoong, Sung Hanbin, Seok Matthew, Kim Taerae and Park Gunwook. Their fans are called ZEROSE.

At Ma Petite Corée you will find the official ZEROBASEONE lightstick, the mini album You Had Me at Hello, the 2025 Season's Greetings and official ZEROBASEONE merch built around the ZERONI: keyrings, plushies and figures. Everything is bought in Korea and shipped from our Seoul office.

ZEROBASEONE discography

From nine members to five

ZEROBASEONE was formed for a limited time with the nine finalists of Boys Planet. The group's contract, extended until March 2026, ended with a final concert as nine on March 15, 2026. Zhang Hao, Ricky, Kim Gyuvin and Han Yujin then left the group and re-debuted in May 2026 as part of AND2BLE. The five other members carry on under the ZEROBASEONE name, still with WAKEONE. In September 2026, Matthew and Gunwook also launched the group's first unit, ZEROBASEONE EMP.

The official lightstick and the ZERONI

The official ZEROBASEONE lightstick is easy to spot with its clear dome on a white base bearing the group's name. It comes with its strap. The ZERONI are the group's official characters: you will find them here as keyrings, plushies and figures. Before a show, take a look at our Kpop Calendar, and find other groups in the lightstick collection.
