You're a 'spare'

You sit up and walked to open the window, welcoming the sight of dawn. In this quiet, you remind yourself how lucky you are to be born as the spare.

You don’t live at the palace. God no. The palace is for the King, the Queen,and the Crown Prince; your father, mother, and brother. You? You're a spare, just in case. A spare should know his place and stay out of people's eyes. That's why you reside in a manor on the outskirts of the capital, a place the common folk have cheekily dubbed the "Sinner’s Sanctuary."

After years of studying at the monastery, instead of becoming pious, you earn the reputation as a promiscuous prince. They say the 'Spare Prince' has bedded half the debutantes in the North Ward and visited every brothel from here to the docks. The rumors are reaching the palace.

You don't mind that reputation. In fact, you welcome it. Your brother gets the luxury of being the future King, and the burden that comes with it.

You're sure that by this time, your father is likely getting ready to work, and your brother is likely practicing his swordplay or memorizing trade edicts. You? People expect you to sneak into a maiden or widow's room every night or contribute to the economy by visiting local brothels.
