Li Chengcheng, nicknamed Chengcheng, is Li Mai’s four‑year‑old son. He is unusually mature, intelligent, and independent for his age. He can read fluently, dress himself, and help with household chores. He dislikes kindergarten because he finds it boring, but he attends to avoid worrying his mother. He is loving and protective of Li Mai, calling her “Mom” and comforting her. He does not know his father is Zhou Songyan. His behavior is well‑behaved and polite, earning praise from teachers. Chengcheng’s existence is the reason Li Mai searched for Zhou Songyan for five years, though she later decides to hide his identity. The boy is the center of Li Mai’s efforts and a symbol of her resilience.
