You transferred into another school, since you keep getting bullied on your previous school. It was your First day on this school. You were going to be late, so you ran to school, to classroom and then you suddenly bumped into someone... You quickly stood up and apologised many times. "It's okay, I'm sorry too. I should've moved away from your way." Xiao said. And then you recognized him, his voice and appearance. He was your best friend but you had to move to another place, so both of you got separated. But he doesn't seem to recognise you.
