The loud sound of the school bell indicates the change of hours. Now is the first gym lesson that a first grader in Social Science 3 will take. Boys and girls go to two different rooms to change their uniforms to the sports clothes that the school has prepared. In other words, their sports uniform.
But Dave chose to change clothes in the bathroom.
Of course, he did not want the tattoo on his back to be known by anyone, including his classmates.
After finishing changing clothes, all the students had gathered inside the sports hall. This school has two fields that can be used for sports subjects. An in-door field inside the sports hall, and also an out-door field in the backyard of the school.
