Liu Weiwei (played by Sun Yihan), a sophomore girl, met art teacher Zou Ye (played by Song Ning) at school. Zou Ye's unique temperament and manners made her feel heart-pounding for the first time. Even though this ignorant feeling that could not be hidden could not be suppressed, the boldness and self-righteousness unique to adolescent girls made Liu Weiwei immersed in the emotional interaction in her imagination and couldn't extricate herself... In that summer, she was like a shining light, doing what she liked and loving the people she liked without any scruples.
