At G-Dragon's 'G-DRAGON 2025 WORLD TOUR [Übermensch] IN KOREA' concert held at the Goyang Sports Complex in Gyeonggi Province on March 29 and 30, a Chinese couple caused controversy by openly smoking electronic cigarettes. A fan named "A" who attended the concert on the first day expressed disappointment on social media, criticizing the Chinese fans' behavior and lack of concert etiquette. The couple not only ignored warnings from security about smoking during the performance but also continued vaping once the guard moved away. The incident, captured in a video shared online, sparked backlash from netizens who questioned the couple's disrespectful behavior and lack of regard for concert rules. The incident serves as a reminder of the importance of proper concert conduct and respect for others in shared spaces, particularly at international events attended by diverse fan bases.
