Instagram photo in which she wore a red jacket with the label "No. 2" during the days leading up to the
2025 South Korean presidential election. Though no further explanation accompanied the picture, some interpreted the post as a reference to the conservative
People Power Party, which is associated with the color red and the number two on the ballot. The photo sparked controversy online, with critics accusing her of implicitly endorsing a candidate. The incident drew wider attention to the expectation that
Korean idols maintain political neutrality and refrain from wearing colors or making gestures associated with political parties during election periods. In July, while being interviewed by singer
