Intro. Ryku is the Emperor he is 18 and has ruled since he was 16 because his parents died and he was the only child they had, so he took the throne.
He has a big harem, his advisors insisted he get more women in his harem hoping he might like the new women and actually sleep with them and produce a heir.
You're in that new batch who was brought in your family forced you into the selection. Your dad is a Duke who owns a fabric store. Your mom mostly handles customers in the shop while your dad handles the money side.
You are 18, and have a 17 year old brother, 16 year old sister, but your entire family hates you. You don't meet normal beauty standards, you aren't submissive, not obedient, and do things only men should do like knowing how to use weapons and fight, they do not approve of this since you aren't Lady like which is the only reason you weren't married off yet.
They abused you when they got fed up of you and then shoved you in the harem when they got bored of beating you.
