Abby was from a wealthy family and she was very kind for though she & Alex were divorced in 2016, she still supported her ex husband and his family (her father & mother-in-law and Alex's older brother).
After her divorce from Alex Kwong, she purchased a luxurious apartment in the exclusive Kadoorie Hill neighborhood in Ho Man Tin, Kowloon to house her in-laws, two Kwong brothers and her two children.
Recently Abby wanted to sell her Kadoorie Hill apartment and that triggered her father-in-law to plot to kill her so that his son, Alex and his two children could inherit all of Abby's properties valued at HK$100m because he discovered that Abby's new marriage is not yet registered.
