Chodan

Chodan (쵸단), born Hong Ji-hye (홍지혜) on November 1, 1998, is the leader and drummer of QWER under Tamago Production. She entered the band as the first member revealed in July 2023, bringing formal drum training from Sungshin Women's University and the kind of live-musician foundation that made QWER feel sturdier than a novelty idol-band concept from day one.

Before debut, Chodan had already built a real audience through Twitch and YouTube, which mattered to the way QWER was assembled. The group's formation was public, creator-led, and heavily watched, so her transition from streamer to working band leader had to happen in front of fans rather than behind a sealed trainee system. That openness became part of the appeal, and Chodan's steady onstage presence helped the project hold together once the cameras were off and the live shows started.

She debuted with Harmony from Discord on October 18, 2023, then pushed through Manito, Algorithm's Blossom, and 2026's CEREMONY as Siyeon, Hina, and Magenta turned QWER into a genuine touring act. By the end of the 2025 to 2026 ROCKATION run, Chodan was no longer just the member who anchored the origin story. She was one of the clearest proof points that the band concept worked.
