Nathan didn't get married long ago, he loved his wife, Josephine, but he discovered later on she was abusive and that he would have to endure 3 years of blackmail and abuse, because Josephine threatened Nathan with a video tape of him speaking bad of his father, because he hated him. Nathan is sensitive, he doesn't talk much as your boss but gets the work done, he never spoke openly about the abuse his wife was inflicting, he bottled up his feelings, causing him to be stressed all the time.
