Through the encore concert marking the finale of the 2025 world tour, ZEROBASEONE attracted approximately 150,000 attendees. The performance symbolically concluded the journey of the nine members who started from zero (0) and were born as one (1) in a single narrative. The concert lasted about three hours and featured a total of 24 songs.

The concert began with "Nan Bitna" ("I Shine"), and the members showed emotional expressions after the first stage. Kyubin said, "We had the first show of this tour here, and standing here again feels touching," while Jiwoong shared, "It reminded me of Boys Planet, and it felt like starting again." Ricky added, "All our songs feel sad," expressing his regret.

Unit stages were also featured during the concert. Jang Hao, Kim Kyubin, and Kim Jiwoong's "Out of Love" stood out with its refreshing atmosphere and sweet vocals, while Park Geonwook, Han Yujin, and Ricky performed powerful choreography with "Step Back." In the latter part, popular songs such as "Doctor! Doctor!", "Love Sick Game," and "Devil Game" were performed consecutively, further raising the audience's excitement.

Notably, the stage for "Lovepocalypse" was unveiled for the first time during this concert, and the members performed "Blue," "In Bloom," "Not Alone," and "Running to Future" on the encore stage. During the "Not Alone" performance, the members shared their emotions with tears. Seong Hanbin said, "There were so many tears. Seeing so many Zerose crying made me even more overwhelmed."

After the concert ended, the members expressed their gratitude to each other with tears. Seong Hanbin said, "Time feels cruel. I want to thank the beloved members and Zerose whom I may never meet again." Jang Hao expressed regret, saying, "We practiced saying goodbye for two days, but it still doesn't feel familiar." Han Yujin said, "We're not really saying goodbye, but this is the last time we perform on stage as nine."

ZEROBASEONE was formed through Mnet's audition program "Boys Planet," and after this concert, the group will continue activities as a five-member unit consisting of Seong Hanbin, Kim Jiwoong, Matthew Seok, Kim Taerae, and Park Geonwook. The remaining members will return to their original agency, YH Entertainment. ZEROBASEONE concluded their 2 years and 6 months journey, cherishing precious memories with their fans.
