Each of us has had a period of youth, and that period can be said to be the happiest period. People who are in love have the purest friendship and the purest love. I believe that most people have had their first love during this period, but the story of this and first love can only be secretly hidden in the heart without anyone listening. My original intention in writing this is to share with you the story of my first love with my classmate. During the period of first love, it can be said that you have tasted all kinds of tastes in the world, from sweetness to breakup, and finally unforgettable. Maybe this is youth.
