This is the information I've collected from other sites and forums. I just want to put everything together; it is not an update entry on the series.
It appears that the above names, especially Gallen, Kenix, Ray, and Jamie are confirmed. Anita Yuen will play Gallen's wife. Kenix-Ray-Jamie will have a love triangle relationship with Jamie being Ray's legitimate wife while Kenix will be his soulmate. Nancy might play Ray's mother.
Kenix's character will be a lawyer. It looks like another strong, independent role for Kenix but this time, I hope her character will have inner conflicts with twists and turns. I dread another role like Kit in Take My Word For It.
While I was hoping that this will be a second collaboration of Kenix and Gallen, the idea of pairing Kenix with Ray is equally pleasant. I like Ray as an actor, especially his role in The Upheaval with Idy Chan in 1985. I'm looking forward to watching them together as a couple.
The filming will likely start in late November.
Warning: a lot of the information on the characters' relationships above is still rumors. As we all know, TVB likes to change their script everyday so don't put your hope too high.
