The brief introduction of my first love story is unrequited love

Zhu Qianshuang's middle school days, when she was a fat girl, fell in love with Qiao Ye, a male classmate who was high above the school, but she was afraid to confess and had to make up her mind to lose weight. After trying various methods to lose weight, such as dieting, taking diet pills, inducing vomiting, electrotherapy and so on. Zhu Qianshuang not only didn't lose weight, but was ridiculed by people around him.

I wish Qian Shuang's persistent efforts for a long time were returned to the original shape, and this unrequited love ended in vain. After graduation, they went their separate ways, as if they had never prepared for any intersection, but what she didn't know was that the joys and sorrows she experienced also happened to Qiao Ye, but they didn't express themselves for various reasons.

Two people who taught each other to be brave missed it and disappeared into each other's youth.
