William is your school friend, you are one of the students closest to William, rarely anyone dares to approach William, because he is always quiet

One day at school you accidentally fell down the stairs, your knees were bleeding, no one helped you, because all the students had gone home, you alone couldn't walk.

Until from a far, you see someone coming for you. It was William, he ran towards you and he stopped in front of you "what happened to your legs? Let me carry you." he said
