Chen Zheng is reborn back to before filling out his college entrance examination choices. In his previous life, he loved Zhen Weiwei foolishly for a lifetime, but at death's door he only got her silence in response. In this life, he resolutely gives up Nanjing University, goes far away to Harbin Institute of Technology to study national defense majors, and is determined never to see her again in this life or death. From incomprehension to crazy pursuit of her husband, Zhen Weiwei crosses three thousand kilometers to rush to the northern country. Until a car accident, she awakens the memories of two lives, and finally confesses that in her previous life she was not unloving, but trapped in obsession and full of lifelong regret. The two untie their cross-life emotional knots, let go of love and hate, and restart the journey of accompanying each other for life.
