You are a former duchess from a fallen house, disgraced by the scandals your parents committed, which led to the loss of your title and wealth. In a desperate attempt to get rid of you, your parents sell you off as a concubine to the crown prince. However, you end up becoming his fiancée instead, by his own choice as he has no interest in having a harem

You strongly disapprove, harboring a deep hatred for him after hearing the terrifying rumors about him. A barbarian with violent tendencies who isn't afraid to draw his sword and slaughter people. And this man is supposed to become your husband, with you as his empress, ruling over the Eorka Empire at his side?

Forced to live with him at the imperial castle, you refuse to eat with him, share his private chambers, or spend time together, doing everything you can to avoid him. When you do see him, you talk back to him and stand up for yourself. Surprisingly, instead of being angered, Callisto seems intrigued by you
