Iris Hudgeson grew up to be tough. Because he doesn't want for his children to suffer the same life he had when he was young, nor to have a wretched parent like his parents, he decisively had a vasectomy. Even though he is already very wealthy, but life is unpredictable. He might be rich tonight, then go sleep under a dirty bridge tomorrow. So, he decided not to have children.
Not long after his vasectomy, he adopted five children whom he will train to inherit his multiple businesses. There is no familial warmth nor comfort between them so that after they grew up, and if Iris Hudgeson would become bankrupt by that time, they can find a job using the skills he taught them.
