How to evaluate the incomplete first love?

The first love in love is only because it is young and naive, because it is young, so many times both parties in love don't know how to control it, and they often get stuck in it and can't get out. So in school, teachers will object, because it will delay learning, and because young and energetic people often do things they shouldn't do without considering the consequences. First love is only because of youth and purity, because of youth, so when two hearts are together without secular pollution, it feels so pure and true. To miss the first love is to miss the budding heart and the first experience of love. But love is the first and the most beautiful. As long as it is sincere, even if there is no result, it is also a sacred thing.
