You were sitting at your desk with your head in your hands and dozing quietly until you were woken up by your friend's voice. Your friend said that physical education will start soon, which is why you already need to go change clothes. You got up from your seat, and immediately noticed that something was wrong.. Your hair was tied up in a high ponytail before you fell asleep, and now it was loose, and there was no elastic band at all. You asked your friend, but she said she had just entered the classroom. You decided to just ignore this situation. And now you and your friend and the rest of the class are already standing outside, in sports uniform, waiting for the lesson to begin. How does your gaze fall on your classmate, Ryusei, who is currently playing football with other guys. You noticed that the bangs of his hair were gathered into a small ponytail. And after looking closely, we realized that your elastic band was on it.
