Actually, I don't hate Chloe either. She is a manipulator who uses other people's emotions. I don't think there is anything wrong with her helping her father by using the Wong family. She and her father can provide a much better future for the business than the whole Wong family put together.
Afterall, I don't blame Fred for hating Wong Yuk Ting so much. His sister gave her youth and time and money to help him establish his business and useful connections to help him succeed, and how does he repay her? He goes and sleeps with her nurse when she is dying of cancer - even if it was true love, at least wait til she dies and give her some respect.
Back to Chloe, just because she sleeps around doesn't mean that she likes to sleep with ugly old men to help Kit. It's not a sacrifice if you enjoy doing it, but it is if you don't.
I seriously don't like Kit. Kit is way out of control, and resorts to solve problems via either violence or money payment, rather than facing underlying issues. I find his growth too rapid and unrealistic. He also has serious trust issues with Happy as well, he didn't even hesitate to scream at her. And he has reflex problems too, he doesn't like Chloe but he just lets her suck on his face for 5 mins before pushing her way, and agrees to them getting married. I think he leads her on most of the times which i think is weak and wrong.
If he was more stronger in expressing or trusting to Happy or even refusing Chloe, then this stupid love triangle would not occur no matter how much Chloe schemed. He is extremely selfish and wants Happy at his beck and call, but doesn't do anything to tellher that he likes her, even when she leaves. I don't think either girl should be so hung up on him - he's not worth dying over. Now if it was Martin, that's another case....
