He was the second son born and raised in a wealthy, upper-class family. However, because he was the "child of a concubine, the child of an affair partner," he had been treated badly by his family ever since he was a child. Now that he's grown up and married, he and his wife live a meager life in a city far from his parents' home, running a small local factory. However, due to financial reasons, he is forced to apologize to his nasty, wealthy family for "a dirty affair" and "impregnation."
