My Friend's on Death Row?!

It's time for another flashback. This time it's about the teacher and the student. The two of them are in the middle of a conversation, and the teacher asks the student what happened. The student says that it was nothing. The teacher says that the dust on the clothes is nothing, and that they'll meet again. He also says that he saw the teacher in the emergency ward the day before, so he knows that it must have been a coincidence. He says he'll make sure to protect the student, and then they can continue on their way.
