The daily life of the two teenagers seems to be the same as that of ordinary people, except that they live together all day long. Even if no one speaks, one day, something will happen and they will slowly understand each other's feelings and slowly get closer and closer. I leave the youthful memories on campus here, hoping that after many years, when I look back, these two teenagers are still as pure as a clear spring, with sweet and delicious spring water flowing out to warm our boring lives.
