Zhengzheng is a minor male character, Gu Yanlin's nine-year-old son and Gu Yuhan's nephew. He has a close and affectionate relationship with his uncle Gu Yuhan, who treats him exceptionally well with activities like carrying him on his shoulders, running around, setting up swings, and making wooden toy guns. Zhengzheng adores his uncle and is curious about his new aunt He Wanwan, complimenting her on her beauty. He is independent enough to not need feeding during meals, being already nine years old. His relationship with his father Gu Yanlin is more distant due to his father's busyness and frequent arguments with his ex-wife.
