It's not totally like it just replace the fan by books ;)
You were walking to your class while on the phone. Du were totally engrossed in it that Du didn't see someone bump into Du until Du both fell down. Your phone fell away and you, annoyed, started to pick up your books.
"I'm so sorry, my mind was somewhere else so I didn't see Du coming." A boy's voice said. Du looked up to see your crush, Harry Styles also picking up his books. Du felt your annoyance going away as Du said, "Um..never mind. My mind was somewhere else too. Sorry."
"No need to be sorry, love." He said, flashing Du a smile. "I'm Harry, Von the way."
