Shen Shenqing is a low-level executive working in a medium-sized company. Her husband is university senior Peng Pai, the man she loved so much back then. His gentle and quiet look, with a shy but sunny smile, could make her giggle at the railings of the stands all afternoon. They got married naturally, but lived in poverty. Until her husband suddenly became successful one day, and she became what others called "Mrs. Peng". At this time, she found out that her husband disliked her and cheated on her. She no longer felt the meaning of life. When she was confused, she traveled back to her college days, which was the best time for her and Peng Pai. But in a daze, she couldn't tell the truth. She thought she would stay away from him this time, but that was not the case. She seemed to feel that he was not him at all, as if Peng Pai in college could satisfy all her fantasies... As everyone knew, Peng Pai had already changed, and he had also come to the future.
