ZEROBASEONE came out to support WAKEONE labelmate Kim Jae Hwan at his year-end concert.

On December 16 KST, the 'Boys Planet' project boy group surprised the audience of Kim Jae Hwan's solo concert, which was held at KBS Arena in Gangseo-gu, Seoul. During the show, they performed their songs "CRUSH" and "MELTING POINT."

Kim Jae Hwan introduced them by saying, "The name of today's concert is 'NOT ALONE,' so I invited friends, ZEROBASEONE. They're very busy people, but they came all the way here. Thank you so much. We're like a family, very supportive. They're rookies with great talent sweeping the rookie awards these days. Even more so, they're auditionees like I was, walking a similar path, so I sincerely want to support them a lot."

The ZEROBASEONE members showed gratitude by warmly responding with, "Kim Jae Hwan has become a family and a significant source of support. It's an honor to stand on stage as concert guests." The heartwarming chemistry earned enthusiastic cheers and responses from the audience.

Meanwhile, Kim Jae Hwan's 'NOT ALONE' concert was held on December 16 and 17.
