Dajun still lives with his father, who dates and plans to marry a ditsy starlet. The boy's mother is a flight stewardess, hence often away, and so Dajun's chubby cousin Yifen is often hired in as a child-minder. The relationship between Dajun and Yifen is, to say the least, abrasive, and Yifen bitterly resents being imposed on--especially when it seems that her own family is keen to get rid of her.
