The crazy princess and the barbarian of the North... Some would call it a perfect match, but neither is truly what they seem: Chloe was only branded as insane by her stepmother as part of a plan to assassinate her, and Callios is a fallen prince who cares deeply for his people. Chloe may have succumbed to her stepmother's schemes in her first life, but this time, she's determined to take revenge with the perfect ally at her side! Can these two make the empire pay for destroying their families? Original Webtoon: KakaoPage, Daum Official Translations: English, Japanese

Elio, a country count's daughter, gets caught up in her father's scheming plot to seduce a young duke. Without even laying a finger on him, she overnight becomes a "trashy young lady" who allegedly assaulted the imperial princess's fiancé. However, instead of setting the record straight, the young duke fans the flames of the scandal. To help Elio escape her abusive father, he proposes a deal: pretend to be his fiancée for three months. Thus begins their fake engagement. The only problem is that she keeps getting shaken, as if it were all real.
