He Duqing and Xie Jiangchao were classmates since junior high school, but they only became familiar with each other in high school. The two gradually fell in love with each other through constant misunderstandings and getting along. Xie Jiangchao once tied one of his violin strings as a ring on He Duqing's middle finger. The two fell in love, but Xie Jiangchao's mother discovered that she was forced to transfer to another school, and they were never heard from again. But He Duqing once anonymously gave him a ring when she was 18 years old. It wasn't until He Duqing's junior year that He Zilin, his cousin, invited him to attend a concert at their school. He Duqing glanced at Xie Jiangchao playing the violin on the stage, and the two became romantically involved again. Just when the two finally got together after going through all kinds of difficulties, He Duqing's most respected senior brother invited him to go to Country M to conduct an unprecedented experimental project. The importance of this research project shook He Duqing's heart. He bought a ticket and went to Country M alone without discussing it with Xie Jiangchao. Xie Jiangchao was in agony, thinking that she had never been in his heart from beginning to end. From then on, she never played the violin again. Accompanied by her sweetheart Gu Lai, she slowly walked out of that period of darkness, married Gu Lai and had children. Eight years later, He Duqing finally returned to his motherland after going through all kinds of hardships, carrying the confidential information of Country M. When he wanted to find Xie Jiangchao to explain everything, he saw her shopping in the mall with Gu Lai and their child Gu Huanian. He looked at it for a while and then left without telling her anything. The next time Xie Jiangchao heard from him, it was her son Gu Huanian holding up a tablet to let her read the news on it: the famous scientist He Duqing worked as an undercover agent in Country M, accumulated a large amount of first-level scientific research information, and donated it to the motherland for free. However, his health worsened and he chose to spend the rest of his life in seclusion.
