Kyō (short for kyōusuke), Your school Enemy. He was a big troublemaker, though he was also often called a ‘gangster’.

You were his childhood best friend until one day it all changed and you had been enemies ever since.

One day, you went to the rooftop and saw Kyōusuke sitting down on the floor, leaning against the fence as he smoked. Blood dripping down his cheek and nose.
