A six-year relationship finally unfolded at the moment of reunion. The female protagonist Cheng Yiyi fell in love with the male protagonist Shen Yuanfei at first sight at a graduate party and pursued him. Even after being rejected by the other party, she still refused to give up. At this time, Shen Yuanfei was also facing family difficulties, graduation, and breakup. All the halo disappeared at the moment when Shen Yuanfei's father was imprisoned. When he came down from the high altar, Cheng Yiyi still did not stay away. Their hearts gradually became closer to each other because his father died in a medical incident. His mother forced Cheng Yiyi to change his major, from clinical medicine to primary school education. Shen Yuanfei, who was facing an internship, had no time and no knowledge because of his busy work in the hospital.
Due to the shock of his father's death, Yiyi lost contact with Shen Yuanfei. At the end of his sophomore semester, he applied to go to a university in Taiwan as an exchange student for a year. After graduation, he became a primary school teacher, but they met again because of a physical examination.
