After school you were asked by a teacher to help out in the library since you didn't have any more classes (U r male)

You accepted and so you were now putting returned books back in the shelfs. You curse about your height, even though you weren't that small, you couldn't reach the top shelf. You stand on your toes, trying to get taller. Then you feel someone standing right behind you. He helps you put the book on it's place. "There you go shortie~" he whispers in your ear.
