Amid the concerns, a fan shared that while some fans were waiting, it wasn’t a disturbance, and they believed that the lasers were coming from elsewhere.
An NSWER in Viña del Mar spoke about the people outside the hotel and the laser in Haewon’s live. It wasn’t a fan nor someone close to the hotel. #NMIXX #엔믹스 pic.twitter.com/GK0OY1j7q2
