From jointly operating a subdivided flat to opening their real estate company; from being best partners to a married couple, Matt Yeung and Samantha Ko are partners in work and life. Samantha has had to fare on her own since she was young.

Not wanting Matt to be left with nothing when he is released from jail, Samantha uses her daughter to get close to her ex-boyfriend, Kenny. Because of her excessive greed, she and Matt ultimately break up their partnership! The deeper the love, the deeper the hate, the two become enemies from then on...
