Our hero is the son of a district lord. His dad is a greedy and arrogant playboy.
His mom is from a good family, but she gets fed up with his dad and runs away.
Even now, his dad's attitude doesn't change. Our hero vows never to become like him.
Upon entering an elite private school, our hero finally gets to move out of the house, away from his dad! Before he even graduates, his father passes away; there aren't many tears shed. He receives a letter of appointment to be the new lord of the now vacant district.
Childhood friends, classmates and maids are waiting for him. He now has the power to control all of them!
