First of all, I hate all three sisters.
I can empathsize with Bik Wan (Kiki) as she sacrificed heaps for her family while her sister, Bik Ha (Jessica) gets an equal share when she abandoned her family to elope, and her husband, Cheung Hing (Bowie) has always been secretly in love with Bik Ha. She feels insecure as her father is biased towards Bik Ha and she cannot conceive due to Bik Ha (will be mentioned in future eps) while Bik Ha marches in with her own son has the heir to the family business. But Bik Wan is so abrupt and rude and stupid at times it is hard to root for her. Don't like her but don't hate her.
Bik Ha (Jessica) is just a plain psycho. She is ambitous, selfish, conniving, and two-faced. I am glad that Jessica too this role as it is very different from her other roles, but right now, I don't get why she has to get out of her way to get rid of her elder sister. She plots against everyone and for what? She abandoned the family in the beginning and now she wants to come back and take everything?
The series is trying to keep her motive a secret, but i guess it would turn out to a mother trying to fend for her son. This is a terrible reason. No one is mistreating her son in the first place (until she starts attacking Bik Wan) and even if he doesn't get all of the family business, it is not likely he would starve or be abused. he can grow up and get his own career, no need to destroy her sister for this. I mean, what on earth did Bik Wan do to Bik Ha (up to ep 5 of course) that she receives this hostility? And to blame her husband's accidental death on Yiu Sang (Michael Tao) is crazy as well. Hate Bik Ha.
Bik Lum (Macy) is supposed to be innocent and friendly, but she is extremely psychotic as well. She makes death threats towards her "stepmother", Lai Sheung (Joyce) and is extremely verbally abusive towards her for a rich highly-educated lady. Don't get why she is so hostile as well. I understand she feels Lai Sheung was a third wheel in her father's everlasting love towrads her mother, but this is confusing as her mother died a decade ago and Lai Sheung only met her dad one year ago. But to be violent and abusive to a pregnant woman? That's just crazy and over-reacting. Hate Bik Lum as well.
Other characters seem more interesting and rational.
Firstly, the sympathetic son-in-law, Cheung Hing (Bowie) who was coerced into a loveless marriage by his father only to be treated poorly and abused by his father-in-law. His wife orders him around like a servant and other people look down on him. Bowie does a very good job as the subtle underdog who will be a great villian later. Really felt sorry for him when he was forbidden to worship his dead father due to his father-in-law's funeral. No wonder he wants the family dead. I like Cheung Hing and look forward to his change to the dark side.
Then there is greedy and opportunistic cousin, Yiu Sang (Michael) who orchestrates a plot to get part of the inheritance his uncle built from his aunt's family pearl (Yiu Sang's mother's side). He is irresponsible at times but he seems interesting for future episodes as he is only putting up a front so he would not be suspected as he is really intelligent and resourceful underneath. Nice comeback for Michael.
Lastly, Lai Sheung (Joyce) is the greedy mistress of the sister's dad (Lau Kong). She is harmless even though she wants the money and appears to be only a pawn used by Yiu Sang to get the inheritance. She might have some kind of a back story behind her but her motives for plotting are much more acceptable than Bik Ha's. Joyce looks really pretty here. Her subtle acting is good at times, but she tends to overact a lot when Lai Sheung is threatened by Bik Lum. Hope she has mroe serious scenes later as Joyce really excels in emotional scenes. Lai Sheung is quite likeable compared to the other females.
