It stars Fann Wong in two diverse roles - a quiet and nondescript cartoon illustrator with a quirky sense of style (Yixin), and a stylish, vampy air stewardess who lives the high life on her motorbike (Joe Ann).

The series title literally means "person in the mirror" and alludes to the main character A young Yixin (Fann Wong) watches her father get stabbed to death in a park by a teen delinquent Jiansheng (Thomas Ong) who is later sentenced to 17 years in jail.

Psychologically scarred by the memory of her father's death, Yixin grows up bitter and vengeful, even though she appears docile and sweet outwardly.

One day, their mother, Esther, decides to escape with the children but unfortunately leaves Jiansheng behind.

He returns to Singapore, where he meets the cool and mysterious Joe Ann.
