Forrest Cat

Fat Cat, originally surnamed Lai, lost his father before he was born. As a child, he suffered severe jaundice that caused brain nerve damage, resulting in moderate intellectual disability, and he was rejected by his relatives in the Lai family. His mother, Leung Suk-Ching, took him to settle in Cheung Chau and single-handedly raised him to adulthood. To prevent Fat Cat from feeling inferior due to not having a father, his mother lied to him, saying his father was a sailor who was always out at sea "selling salted duck eggs" to earn US dollars.
Fat Cat's mother has a younger sister, Leung Yuet-Ho, who has a son, Fat Cat's cousin. Fat Cat's cousin often bullied him. Later, Fat Cat's mother moved with him to live in the urban area, and with the assistance of social worker Hong Chun-Ming, Fat Cat worked at a sheltered workshop. Eventually, Fat Cat met a mildly intellectually disabled woman, Li Siu-Fong, and developed a pure romance with her. Due to the forced relocation of the sheltered workshop, Fat Cat and Li Siu-Fong eventually took over her father-in-law's café.
