What's the plot of That Little Thing Called First Love?

Siaoshui is the most ordinary girl in the first grade of junior high school, her schoolwork is average (only English is the best), her physical education is also average, and what's worse is that her looks are so ordinary that people will forget them at first sight. But this ordinary girl falls in love with Liang, the best, kindest and most handsome senior boy in the school. Being the man of the hour on campus, Liang has always been the center of attention for the girls, whether it's good in schoolwork, excellent in sports, or handsome, all the girls in the school are crazy about him. Xiao Shui realizes that she can't compete with those outstanding girls at all, and she only wishes to be closer to Senior Ah Liang. So she does a lot of silly little things just to change herself: she applies to join the dance club but is humiliated by her classmate Fei, who likes A-liang, during the screening; she goes out of her way to act in a play that no one will ever see; and she practices marching music conducting. ...... These are just for the sake of getting closer to Liang.　(In fact, Xiao Shui didn't realize that not only did Ah Liang remember her name with great care, but he also had the good sense to collect a box of chocolates she had given him and keep it in the refrigerator (chocolate cannot be preserved at room temperature in tropical countries). As for Faye, Liang only knows her as the little sister who gave him the mango cake. Stills (19) A-liang doesn't confess to Xiaoshui in person, but everything he does for Xiaoshui clearly tells us that he likes her very much.)　Xiaoshui's hard work has made her a veritable sensation in school by the time she is in her third year. She becomes the sweetest, gentlest and most desirable school girl in the eyes of the boys, but Xiaoshui still has her little wish stored in her heart. Unbeknownst to her, her performance during the drama performance is noticed by Taku, Liang's best friend. Taku confesses his love for Xiao Shui, but Xiao Shui remains silent and goes on a threesome with Taku and Liang, but she still likes Liang. Later, Shizuku tells Taku that she has a crush on someone, but not on Ryo. When they were young, Liang and Tuo, who both had a crush on each other at the same time, became close, and when Tuo was rejected, he asked Liang to promise not to go after Xiaoshui, and Liang agreed out of respect. Finally, at the graduation of junior high school, Xiaoshui finally gathered enough courage to confess to Ah Liang, but found that Ah Liang has already accepted a week ago, Xiaobin sister, the two once again missed. In fact, Liang didn't get together with Xiaoshui because he hid his true feelings out of the promise he made to Tuo at the beginning.　In fact, in the long term, Xiaoshui and Ah Liang both have mutual feelings for each other, but they miss each other again and again. In the end, those words that they didn't have the courage to say are expressed bit by bit with the photos of Ah Liang. This lets us know that Xiao Shui's efforts are not unseen by A-liang, it's just that those unfortunate reasons keep them apart. Later, Xiaoshui went to the United States to study, while Ah Liang became a professional soccer player.　Nine years later, both of them had their own achievements, Xiaoshui became an outstanding fashion designer, and A-liang successfully transformed from a super football player to a photographer. In an interview scene of the program after Xiaoshui returned to China, the host invited A-liang's senior, and after nine years, the two met again ......
