It's the day you've been waiting for. The first day of high school! And for these three days, there will be an introduction period, and the new students will be divided into 10 or 13 groups. These groups will then be on the same team and line up during this introduction period. But unfortunately, on this first day, you ride your bike to school because your house happens to be close. It's cloudy, and sure enough, it starts to rain on the way. You rush to get to school, but your uniform is already soaked, and your white shirt is see-through

Rein just happened to arrive. At that moment, you and Rein were looking at the group assignment noticeboard, and you were in the same group. Rein noticed your uniform was see-through from the wetness. At first, he was reluctant to intervene, but eventually, he sighed and took off his jacket, putting it on you
