Background / History

Koukou is raised by Qiao Wanqing, who initially considers sending him to his biological father, Gu Yanqing, because of her financial insecurity. She ultimately grows reluctant to part with him, despite knowing that the original novel portrays him as a future “deranged big villain.” 3

His presence changes the original story’s expected course. In the original setting, Gu Yanqing was unaware that he had a son and only met Koukou’s mother after Koukou had grown into a villain; in the altered timeline, Gu Yanqing gradually becomes involved in Koukou’s life from infancy. 30

Koukou’s attachment to Gu Yanqing becomes unmistakable when he cries after Gu leaves and immediately brightens when his father returns to hold him. This leads Gu Yanqing to begin calling himself “Daddy” in front of him. 81

Appearance

Koukou grows from an “ugly little newborn” into a fair, chubby, round-faced child with an appearance his family repeatedly describes as adorable. 3

• Fair, rosy-cheeked complexion and a plump face. 90
• Tall and long-limbed for his age. 152
• Strong resemblance to Gu Yanqing. 40 153
• Often likened to a “little prince,” especially when dressed in formal clothes. 129 152
• His appearance can be convincingly feminine in dresses and flower crowns. 90 172

Personality

Koukou is affectionate, expressive, and highly attached to his parents. He seeks physical closeness, remembers Gu Yanqing even after long separations, and waits up for Qiao Wanqing when she is away. 80 180

He is also mischievous and willful. He runs off when unsupervised, pretends not to understand rules he clearly knows, and uses sulking, crying, or strategic cuteness to get what he wants. 153 158 247

Food is one of his strongest motivations. He eagerly pursues formula, snacks, cake, fish, and any animal he imagines can be eaten; he can be persuaded with treats even when frightened of a haircut. 128 135 175 236

Despite his childish selfishness, Koukou is sentimental and capable of generosity. He preserves meaningful objects in a private cabinet, shares cake with Gu Jingzhi after struggling with the decision, and protects his younger sister as they begin kindergarten. 168 237 263

Abilities & Skills

Spirit Urine

Koukou’s urine has an extraordinary fertilizing effect that drastically accelerates plant growth.

• Plants watered with urine-mixed water grow approximately three to four times faster than normal. 7
• Bok choy that ordinarily takes about twenty days to mature can be harvested in eight days. 7
• The resulting vegetables are notably fresh, tender, juicy, and crisp. 7
• Qiao Wanqing incorporates his urine into compost and farm irrigation, making it central to her exceptional vegetable production. 7 102
• Residual urine-based water may be responsible for abnormally rapid growth in later crops, though Qiao Wanqing investigates rather than treating the cause as confirmed. 136

Learning Through Imitation

Koukou learns through observation, repetition, and praise.

• He learns to identify his eyes, nose, ears, and mouth through a clapping song taught by Mrs. Gu. 150
• He imitates adult greetings at Gu Yanqing’s company event and corrects “bye-bye” to “hello” after instruction. 153
• He begins singing after repeatedly hearing a musical toy dog’s song. 240
• He develops increasingly fluent speech, progressing from basic sounds and single words to public greetings and longer sentences. 28 129 153

Relationships

• Mrs. Gu — Paternal grandmother. She is deeply indulgent toward Koukou, teaches him through play, and frequently takes his side against his parents. 112 150 195
• Keke — A baby girl Koukou affectionately calls “little sister.” He touches her face out of curiosity, later places a ceremonial crown on her, and congratulates her at her full-moon banquet. 126 129
