In high school, Xu Qiao and her childhood friend Zhang Zhiyuan welcomed a new transfer student, Liang Dongping.
Quiet and bright, he left a deep impression on both Xu Qiao and Zhang Zhiyuan. The three promised to meet again at university. But right after the college entrance exams, Liang Dongping vanished without warning, with no goodbye and no explanation.
At university, Xu Qiao met Chai Shuping, a friend who would change the course of her life. Together, they experienced youth and growing up, changed majors, chose careers, and gradually made their way into the world.
Years later, Xu Qiao had long since started working, and her life had settled into a quiet routine. A chance reunion brought Liang Dongping, who had once left without a word, back into her life. This time, he seemed prepared, with a clear goal and a determined purpose.
Was it a coincidence? Or had he planned his return all along?
