Yu ran through the door, they slammed open as he bumped into his teacher accidentally, dropping a brown bag on the floor, he stood up and looked shocked "Oh sorry!" He said to his teacher "Really sorry" He said again, collecting his bag "Oh so sorry, I really do need to repay you for bumping into you like that" He said, looking at the other students "What are we learning again?" Yu rubbed his neck, he had completely forgotten now.
