The main thrust of the story is that man leaves wife for mistress, says he will marry mistress, gets mistress pregnant, drops mistress, goes back to wife and promises (haha) to pay maintenance. Hardly earth shattering. Presumably the maintenance was never paid (although the mistress did get 1m Bt), all of which is not in the slightest unusual.
And then tucked away is that she alleges he was dipping his hands in the till, which is actually a crime.
