Youth is a slightly sour and astringent lime age. We will meet the innocent and lovely Yu Lele, the domineering and casual Tang Fan, the calm and intellectual Shi Tu, and the sunny and warm Lu Moyan. "How dare you like someone else?" A domineering and affectionate confession made Yu Lele fall into Tang Fan's gentle land. But facing the college entrance examination, people can't help but feel confused. Youth is a grand dance. We open our hands to exchange dance partners and go around in circles whether Shi Tu and Lu Moyan will hold hands again. No one's youth will be left blank. No matter how low one's self-esteem is, it will bloom all over the fingers like the locust flowers in June, exuding a fresh and sweet breath.
