Hoshi Furu Oukoku no Nina

Nina was forced into a life of crime to survive and was later sold into slavery by her brother. Instead of being treated as a servant, she is given the life of a princess, replacing the recently deceased princess-priestess Alisha. Though her circumstances have changed, Nina resists this new life and challenges Prince Azure, who may be her equal in intelligence. The question remains whether she can trust him, and whether she can suppress growing emotions, knowing she is expected to eventually marry someone else.
