Hong Ji-hye, known professionally as Chodan, anchors QWER as the group's leader and drummer — an unusual dual role in a K-pop landscape where instrumentalists fronting idol units remain a relative rarity. Since the group's debut on October 18, 2023, she has been a defining presence in what the four-member outfit represents: a band-oriented approach to girl group performance built around live instrumentation rather than conventional choreography alone.
Debut & Formation
QWER debuted in October 2023 as a four-member K-pop idol group distinguished by its emphasis on a live band format. Chodan's role within the unit goes beyond a symbolic leadership title — as drummer and sub-vocalist, she occupies the rhythmic foundation of the group's sound while also contributing vocally, a combination that places significant technical demands on a single performer. Her background as an online streamer prior to and alongside her idol career has also shaped her public profile, giving her a degree of direct audience familiarity less common among debut-era idols.
Activities
Beyond the recording and performance work that comes with leading a debuting idol group, Chodan has maintained a visible presence in front of cameras in a variety of settings. In early 2026, she appeared in a photo feature that drew attention for the energy and expressiveness she brought to the shoot — a reflection of the kind of individual profile work that members of active K-pop groups typically undertake between group releases.
