On Saturday, February 21, 2026, three QWER fans known as 'Bawi-gae' embarked on a pilgrimage tracing the footsteps of member Siyoung in Osaka. The fans visited several notable locations in the Namba area where Siyoung had worked and spent time, including the maid cafe 'At Home' where she was employed, 'Cafe Anon' known for its chocolate parfaits that she enjoyed, and the NMB48 theater where she performed for several years. Interestingly, QWER's song 'Worrying Addiction' was playing at the maid cafe, and middle-aged fans of NMB48 were spotted at the theater after attending a concert. During their pilgrimage, the fans also planned to visit 'Wanaka,' a takoyaki chain that Siyoung had strongly recommended. Through this experience, the Bawi-gae fans realized how deeply K-pop idols can influence local culture and regional activities in Japan, while also appreciating Japan's well-developed regional cultural infrastructure.
