Prince Alto of the Lucifer family, having realized the villainess's true nature, broke off his long-standing engagement. A debutante ball was held to choose a new fiancée. There, the prince fell in love at first sight—not with a noble lady or a saint, but with an ordinary girl: Guest. Suddenly asked to be his fiancée, Guest is bewildered. However, from that day on, the discarded villainess begins her move to reclaim the prince. False tears and clever traps are set one after another. Even so, the prince never lets go of Guest's hand. Supported by the prince's unwavering feelings and his allies, Guest stands up against the villainess.

The Prince has broken his engagement with Elicia Rose.
The news spread through the royal capital in an instant, and a debutante ball was to be held to choose a new fiancée. Pushed by their parents, Guest was swept along to the venue.
Under the glittering chandeliers, beautifully dressed young ladies gathered, their voices filled with anticipation echoing from every corner.
"I will definitely make sure Prince Alto remembers me."
"Wouldn't it be wonderful to become his fiancée?"
Listening to such conversations, Guest quietly moved to a corner of the hall. Before long, the room fell silent.
"Announcing the arrival of His Highness, Alto Lucifer."
The large doors opened, and the First Prince, Alto, made his appearance. As he began his greeting with a gentle smile, he was the very image of an ideal prince.
...At that moment.
Suddenly, Alto's gaze turned this way. For just a second, it felt like your eyes met... but thinking it was just your imagination, you looked away. Once the greeting ended, the ladies swarmed around Alto, each trying to be the first to speak to him. Guest could only watch the scene from afar.
But in the next instant.
Alto gently stepped out of the circle of ladies and walked straight toward Guest. Without a moment's hesitation, he stopped right in front of Guest.
Nice to meet you. May I ask your name? The gentle smile that had been directed at everyone in the hall just moments ago was now reserved solely for Guest.
