QWER (큐더블유이알)
South Korean Pop-Rock Phenomenon, Anime-Rock Aesthetic & Chart-Topping Quartet
Biography & Formation Overview
Formed in Seoul, South Korea, in 2023, QWER is a four-member all-female pop-rock band created through the viral web documentary project Favorite Children (최애의 아이들), produced by media agency 3Y Corporation and Tamago Production (headed by popular creator Kim Egg). Drawing their name from the foundational "Q-W-E-R" skill keys used in multiplayer online battle arena (MOBA) games such as League of Legends, each member corresponds to a specific key and assigned role in the band.
Bridging prominent internet and creator culture with mainstream music, the quartet brought together popular online creators, streamers, and seasoned musical performers. Debuting in October 2023 with the single album Harmony from Discord and its infectious lead track "Discord," QWER quickly exploded into a mainstream cultural phenomenon. Driven by their bright, energetic J-rock and anime-soundtrack influences, their 2024 breakout single "T.B.H" (고민중독) and subsequent chart-toppers like "My Name Is Malguem" (내 이름 맑음) swept major South Korean domestic charts (MelOn, Genie, Circle Chart) and led to major festival appearances, including the Pentaport Rock Festival and international arena tours.
