Chen Yanqiu, a female doctor with a doctorate in the Republic of China, accidentally traveled through time and became Su Nianyun, a scumbag student at a modern medical school. He and his classmate Jiang Yuchuan, who were top students, also changed from being "rivals" to admiring each other and developing feelings for each other.
However, after traveling through time and changing his gender, Su Nianyun was troubled by whether he had deceived Jiang Yuchuan or even become the third party between the two.
Is this love that travels through time and space the love that he yearns for, and what choice does he have to make?
