Because she was young, she only became the class beauty; she lacked a bit of maturity to become the school beauty.
She thought she would always be the class beauty and then become the school beauty. But in her second year of high school, a new student transferred to her class, and that was An Ruo.
Although she was not inferior to An Ruo in looks, she was outclassed by An Ruo in terms of charisma, and as a result, An Ruo was crowned as the class beauty and eventually the school beauty as well.
What made Xia Nuo even more depressed was that the teacher arranged for the two of them to sit together.
In the beginning, Xia Nuo always gave her the cold shoulder, but as the saying goes, you can't fight without getting to know each other; later on, they became good friends.
