This story begins in 2010, with a rural middle school as the background.
When Li Dongfang met Yuan Chenxi, she was already the girlfriend of his good friend Yang Yuanyuan.
Until the moment he saw Yang Yuanyuan holding her, he confirmed with pain in his heart that he had already fallen into it. He understands the principle that "brothers and wives should not be deceived", so he can only hide his feelings behind his sharp and poisonous tongue, guard Yang Yuanyuan, and rely on this to stay in Yuan Chenxi's world.
He thought he could always be a bystander like this, until Yang Yuanyuan flirted with other girls and was bumped into by Yuan Chenxi...
Yuan Chenxi is a person with a strong sense of boundaries. She has several faces - she will be coquettish to those close to her, and she will be speechless to those she hates. Which one is the real her? No one knows, only that she always has different attitudes towards different people, and her emotions are all written on her face...
Purpose: Companionship is the longest confession of love
