Karen is the Director of the Administrative Office of Rihian.
She dreamed of a quiet retirement, but one day she received an absurd order from the queen.

—“Look, I don’t want to be queen. Go and find my successor.”

That’s how she finds Erich, a boy with a distant blood relation to the royal family, and raises him. But when Erich grows up, he’s no longer the innocent child he used to be.
For Karen, who has lived her entire life with firm principles, confusion begins when new and very unexpected emotions arise.
