Born with black hair—a trait often associated with villains—Julia has been persecuted by her family and called a “demon.” Because of this, she hides the fact that she actually possesses an enormous amount of magical power and lives quietly. One day, however, she is suddenly chosen as the new wife of King Luison. And on top of that, she is to become the stepmother of his twin princes…!? She intends to refuse, but the moment she meets the angelically adorable twins, she’s completely smitten! However, due to the superstition surrounding “ominous twins” and because the boys have no magic, their future is filled with overwhelming hardship. Seeing her own past in the baseless discrimination they face, Julia resolves to protect and raise them as their stepmother—no matter what! “I will protect the smiles of these twin princes—no one will take them away!”
