The conditions are that she take care of the unfriendly cat he is temporarily looking after, and that she not see him as a romantic interest. Just as they begin their secret life together, a surprising event awaits...!?
「Someday—you will kill me」 Amelia, the hidden head of the Ronan Ducal House, was once betrayed by the man she loved: Eris, the first king. As a result, she was cursed with “the Blessing of God,” which was really a cruel spell that made her immortal. The curse did more than bind Amelia’s life—it forced her to protect the kingdom for all eternity, so long as the bloodline of Iris continued. Seven hundred years passed. At last, the royal bloodline ended when Queen Isolde rose in rebellion and overthrew the king. Yet even then, Amelia’s curse did not break. Crushed by despair, Amelia suddenly found herself summoned by a boy she had never seen before: Felix. Only the first king, Eris himself, should have been able to summon Amelia with magic. Realizing that this boy might be the only Blessed Child capable of breaking her curse, Amelia decided to raise and train Felix—so that he could one day “free” her from this world by killing her…!
