TWICE member Tzuyu sparked discussion on the 16th when she gave a witty response to a critical comment about her appearance on the fan communication app 'Bubble.' A netizen sent a message saying "Can't you lose weight on your legs? The backup dancers are slimmer than you," to which Tzuyu replied "Thank you. Save your money." Bubble is a paid subscription service costing 5,000 Korean won per month, making Tzuyu's response a clever jab at someone paying money just to leave negative comments. The conversation spread across online communities and social media, sparking discussions among both domestic and international fans. In particular, regarding a fancam of Tzuyu from a TWICE world tour concert held on the 15th, some international K-pop fans criticized Korea's seemingly excessive preference for extremely thin body types. In the video, Tzuyu performed intense choreography wearing a short bodysuit and fur boots. This incident reignited debates among K-pop fandoms about the excessive focus on appearance in the Korean entertainment industry. Meanwhile, most netizens supported Tzuyu with comments like "The dedication to leave hate comments while paying for it," "Tzuyu's response is cool," and "Tzuyu has a glamorous body type."
