Yugyeom’s performance at the OCTOPOP 2023 music festival took place on Day 1, Saturday, October 21, 2023, at the Thunderdome Stadium in Muang Thong Thani, Thailand.

Organized by 4NOLOGUE, the two-day festival featured a massive lineup of T-Pop, J-Pop, and K-Pop stars. Yugyeom served as one of the ultimate headliners on the main Atlantis Stage.

Despite a downpour during Day 1, Thai "Octopians" and Ahgases stayed in the stadium to cheer him on. Yugyeom rewarded their loyalty by delivering a completely live, high-energy, and charismatic set in a cool, semi-sexy black outfit.
