Accompanied by the pleasant ringing of the school bell, Xiao Yu hurried to the school entrance carrying an oversized and heavy-looking schoolbag. Xiao Yu has always been a very obedient child, very popular with teachers and elders, but he has never been able to get rid of his habit of being late. Fortunately, the teacher turned a blind eye, and everything has been fine. When Xiao Yu was still five steps away from the teaching building, she suddenly stopped. In front of her was a little girl with a ponytail who looked like she was a freshman in junior high school. She was eating bread and walking slowly towards the door of the teaching building. In fact, it was nothing, but when Xiao Yu saw the wrapping paper that she threw on the ground after eating the bread, she couldn't pretend that nothing happened.
