Whats Sanity? (H2ODeliriousxreader)

The vanoss crew all went to paxs together even delirious with his mask the all sat at they're (booth thinga-mijig) when they noticed there was a new booth acrossed the way. A girl with ginger hair and green eyes and a short girl (you)with a white mask with a blank face with tears streaming down. She had her hair pulled back in a pony tail
Wild cat knows this strange girl and is close friends
After everyone becomes close friends something... Strange happens reveling dark secrets of everyone and ultimately reveling what's behind the mask (physically and mentally)
