Regarding Xia Jing's proposition to stay friends, Zhang Zhentian simply couldn't accept it.
She couldn't bear to see the woman she once loved the most become a stranger after they had been lovers, married, and shared a bed for more than a decade, only to settle for being friends in the end.
Such a result was undoubtedly the greatest blow to Zhang Zheng; it only made him feel as if, being a man, he couldn't even have the very basics, nor could he obtain the love of the woman he desired most. He felt that living in this world with such conditions was utterly meaningless and only brought unbearable pain.
