can someone explain the back story of yuri?

when he was in middle school, both his parents and his unborn sibling died in a fire. The fire was put by a former worker of his parent's company, who thought he was fired because he wasnt good looking. Before the fire, a friend of Yuri's confessed to hating Yuri, because of how looking the latter was, and how bad the former was treated by Yuri's fangirls. He said "I wish Yuri and everything related to him was dead". During the fire, the firemen pulled put the friends body, who was there to apologise to yuri, and attempted to save his family from the fire. He became prejudiced against ugly people because of this.
what??? it ends just like that i want more! ╥﹏╥
