Yoru dake no Cinderella

Stella Greco has a child, Nicky, through artificial insemination and has no desire to involve a father in their lives. The sperm donor is Vasco Montoya, the king of Montmajor, who sees this as an opportunity to secure his family line without a forced marriage. He wants Nicky to live in Montmajor, but Stella refuses to let go of her son. As a compromise, Vasco offers Stella a temporary position restoring ancient texts in the palace library, allowing her to experience life there with Nicky. Neither anticipated developing feelings, though navigating a relationship with a royal proves difficult.
