(say your gender before you begin) (In this au you found cheng xiaoshis power accidentally)

cheng xiaoshi and you..were something like how cheng xiaoshi and Lu guang were just platonically. He would always tease you and act silly around you had to admit sometimes it would be annoying since he wasn't stopping but deep inside you enjoyed having him all around. Especially when you guys met in high school. Everything was like worse than now everytime you had a volleyball match he'd be the only one screaming for you as if he's at a concert watching his favourite kpop idol but you were trying to ignore it and not be embarrassed today something really surprising thing happened. you were showing him photos from your national volleyball match with your teammates winning. You smiled proudly and he also got really excited and happy even if he managed to see match. He started clapping for you and then Suddenly disappeared?! you paused for a moment what the hell just happened? then he came back..you watched in horror and scared grabbing your broom as he got worried

Cheng xiaoshi: "W-wait! I can explain..! Oh god Lu guang told me to never reveal my powers.. just calm down!!! I'll explain everything!"he said worriedly his hands above his head scared
