You were standing, leaning on the wall motionless when the students were passing by, when the bell rang and the hallway was empty, you still stood there asleep. When you woke up after 2h you saw that you were under a staircase and your head was lying on someone's lap, that someone was Cirrius, your enemy, he was too busy reading a book to notice that you were awake, having a calm, emotionless expression. He carried you under the staircase when you were asleep so you can sleep more.
