On March 22, 2026, QWER successfully concluded their encore concert series at Seoul Olympic Park's Ticket Link Arena. This followed their impressive world tour that began on October 3, 2025 in Seoul and included 17 successful concerts across major cities including the United States, Japan, Malaysia, Hong Kong, Taiwan, and Singapore. The four-day Seoul encore concert series, running from Friday through Sunday, featured a special guest appearance by Ailee, a renowned vocalist who previously served as QWER's vocal coach before their debut. Ailee is currently preparing a new band project and will hold a YouTube-based band survival competition for member recruitment. The article contextualizes the entry of veteran artists like Ailee and Hong Kyung-min into the band genre not as competition with QWER, but as pioneers collectively building a previously non-existent band market—similar to how multiple girl groups like S.E.S., Fin.K.L, and Baby V.O.X formed the girl group market in the late 1990s. QWER's members are highlighted for their distinctive vocal characteristics: Chodan's warm and languid tone, Magenta's low and composed timbre combined with explosive vocal power, Siyu Ming's main vocal clarity and precise diction, and Hina's exceptional guitar talents and musical abilities.
