Song Chuhuai is Song Chuman's six-year-old twin brother. He is brave, loyal, and fiercely protective of his sister. When Li Cuicui orders them to throw Chuman away, he blocks his aunts and shouts that he won't be polite if they touch her. He also helps his mother hold onto Chuman. After the family division, he works alongside his sister to clean the mountain cave, carry water, and gather firewood. He develops superhuman strength at the same time as his sister, which he attributes to the Sea God Madam's compensation. He follows his sister's lead in digging for seafood, quickly adapting to her instructions and helping to fill the bucket. He is excited about eating good food and is eager to support his family, showing great maturity for his age.
