Nope. Yuri's parent's died in an accident. I guess the glasses guy either was a good friend of Yuri who also managed (nearly) to pierce through his heart or he admired Yuri in the past and stuck close to him. And git bullied in return. I guess he in his desperation burnt something down and accidentally caught their house affire and causing him burnt marks. If he burnt down Yuri's house wouldn'e he be in jail?
Is that why he doesn't like them? Because an ugly person burnt down his house and killed his parents?
