ONF will hold its first solo concert, "ONF 2021 LIVE CONTACT: CODE #1. [REVERSE]" at YES24 LIVE HALL for four days from December 9th to the 12th and will meet their fans face-to-face in about two years.

This performance will be held offline for two days on December 9th and 10th, and online and offline performances on the 11th and 12th at the same time to communicate with more audiences. In particular, the pre-booking for the fan club, which opened on the 9th of last month (November), showed off all-time ticket power by setting a record of selling out four offline seats within a minute of ticket opening.

The concert is the first solo concert since its debut and the first face-to-face performance in about two years, drawing keen attention from numerous fans. The 6th mini-album 'Goosebumps' was released on December 3rd, and all the Korean members are about to enlist at the end of December, so it has been a hot topic of interest.
