Gu Ansheng, played by Zhou Junwei, studied in Top Gun. He is handsome, warm and kind, and has guarded his sister Gu Anxin since childhood. He gave Gu Anxin all the best things. At first, everyone thought that Gu Ansheng's love for Gu Anxin was his brother's love for his sister. It was not until later that he knew that Gu Ansheng always liked Gu Anxin. He buried this feeling in his heart for many years. When he saw Gu Anxin and Yue Ling together, he slowly showed his love for Gu Anxin.
After experiencing some events, Gu Ansheng found that Gu Anxin was happy only when he was with Yue Ling, so he chose to let go and fulfilled Gu Anxin and Yue Ling. After all the dust settled, Gu Ansheng took the responsibility of taking care of the whole family.
