One common theme would be freedom. The slave would probably strive for freedom from the king's control. Also, loyalty could be a theme. The king might expect loyalty from the slave, and the slave might have to decide whether to be loyal or rebel. Another theme could be identity. The slave may have to struggle with their identity as a low - status individual in the king's court while also having their own sense of self.
The theme of transformation is also prevalent. The slave often transforms not only in social status but also in character. They might start as meek and submissive but end up as strong and influential. This can be seen in many ancient stories where the hardships of slavery mold the slave into a more resilient and capable person who can then interact with the king on equal or near - equal terms.
One common theme is the transformation of the relationship. Initially, it's based on the power of the king over the slave. But then it often shifts to something more equal, like friendship or mutual respect.
One common theme could be the struggle for freedom. The boy slave in the novel would likely be constantly fighting against the oppressive system that enslaves him. Another theme might be the loss of innocence. Through the hardships of slavery, the boy would have to grow up fast and face cruel realities, losing his childhood innocence.
Power imbalance is a common theme. Usually, the slave girl is in a position of less power compared to other characters. For example, in some novels, she might be at the mercy of a powerful lord or a magic user.

The main character has to navigate complex relationships with the members of the harem. In 'Date A Live', the protagonist has to understand and bond with the different female spirits.
Love and passion are common themes. The relationship between the king and his mistress is often a love that defies social norms.
The theme of survival is key. Concubines are in a precarious position in the palace. They have to deal with jealousy from other women, the king's fickleness, and the strict rules of the court. So, they must find ways to survive, whether it's by making alliances or using their wits. In many novels, the concubine's journey is centered around her fight for survival in this cut - throat environment.
One common theme is oppression. The slavery aspect represents a form of extreme oppression, and in the science - fiction context, it can be used to explore how different systems or technologies can be used to subjugate people. For example, in some works, there are advanced civilizations that enslave others based on genetic differences.
Power imbalance is a very common theme. The master has authority over the slave, and this creates a dynamic that drives the plot. Another theme is loyalty. The slave may show extreme loyalty to the master, or the loyalty may be tested in various situations.
Resilience is another theme. Despite the difficult circumstances, the slave girls in these novels usually show great strength. In 'Beloved', Sethe has to come to terms with her past as a slave and still tries to build a life for herself and her family. She endures so much but still has an indomitable spirit.
