Guandeng, also known as Turning off the lights or Lights Off, is a male streamer in the Voice Hall who acts as one of the teachers Nan Que interacts with during the Start the Train game. He has a playful and teasing personality, making Nan Que use a cute, coquettish, breathy voice to call him Brother. He laughs wildly at Nan Que's performance and approves him to move on. He also tries to stop Nan Que from cheating with Xiao by being too soft, telling Xiao not to go easy on him. He speaks up to defend Nan Que when Hua Rong accuses him of leeching, saying it is all just show effects and not to take it seriously. He is one of the more experienced streamers in the hall who enjoys teasing newcomers but is generally friendly and supportive.
