No idea why all the women were falling for Joe. He is really slimy and kind of ugly (no offense to the actor). They came across as desperate and clingy, quiet pathetic and not the kind of women anyone could respect.

All the bad people got their karma.

Gift lost her child and husband, also has to live with the guilt of being partly responsible for Tooms death.

Toom got her karma for being Joes mistress while pretending to be Gifts innocent cousin.

Joe got his karma by loosing everything and knowing he is responsible for someone's death.

All in all a satisfying ending, although most of these Thai dramas seem to have the same storyline with different characters. If you've seen one, you've seen them all.
