Kokichi Ouma was not a typical 'social butterfly'. Throughout high school, he'd been a typical 'class clown', and made a few friends through his jokes. Otherwise, he had kept his head down. He was small, jokes were an easy defense to the taunting. High school then passed quickly, and the looming threat of college had hung over him.
So he ran.
Perhaps not in the sense of running away, but in the sense of a 'fresh start'. College would offer him escape from the city he'd known all his life, even if the city he had grown up in was rather large. Not to mention, it offered him an escape from his family. He had never been terribly close to his parents, a loose term- legal guardians was more appropriate, so he felt no guilt moving to some far away town.
The only issue with fresh starts was how fresh they really were.
College was less of a breeding ground for idiots, bigots, and douchebags than high school had been. There had always been the odd person or two to get on his nerves, but as a whole it was a far better experience than what he was used to. He socialized much easier here, letting a naturally extroverted personality take hold and let him interact with others. He certainly wasn't a fraternity type, but he was involved enough to make some friends all around.
His classes were a different story, and some of the general classes he had held people who were far beneath him. Crude, close minded, and unintelligent. A perfect combination of three things he couldn't stand. So in some of his classes, he didn't bother to socialize.
