Zhang Yi'an graduated from university in July 2007. After graduation, he worked in a water conservancy design institute in Yichun City, Jiangxi Province. During the Spring Festival of 2008, Zhang Yi'an returned to his hometown in Jilin to celebrate the New Year. He accidentally fell while playing on the ice and suffered a brain injury. He lost all his past memories. His cousin Zhang Jiahuai sent him back to Yichun, Jiangxi Province to work. During the hospitalization, Zhang Yian met nurse Peng Yuting. After being discharged from the hospital, Peng Yuting took the initiative to date Zhang Yian. After the two confirmed their relationship, Peng Yuting invited him to live in the red building of Yichun Vocational and Technical College. Their relationship became deeper and deeper during their daily companionship. The two visited Yichun attractions together, met their parents and made a lifelong commitment. Their life was sweet and stable. In November of the same year, during a basketball game, Zhang Yi'an accidentally fell again and lost the memory of his eight-month relationship from the Spring Festival to now. Peng Yuting suppressed her grief, followed her best friend's plan and moved to rent across from Zhang Yian, starting from scratch and getting closer. After experiencing misunderstandings, twists and turns, and an incident with childhood sweetheart Tang Yushan, Zhang Yi'an finally fell in love with Peng Yuting again. The two reaffirmed their relationship and met their parents together to prepare for their marriage. After his grandmother passed away, Zhang Yi'an was given clues by a dream, and with the evidence of the diamond custom-made order from Lao Fengxiang Silver House, he began to search hard for the lover in that period of amnesia. Finally, when watching "Nine Beauties", his memories were triggered, and he remembered that Peng Yuting was the lover he had been looking for. Finally, they embraced and renewed their relationship in the red building where they first lived together.
