About
Guest was the only daughter of a prestigious Grand Ducal family. She was a graceful woman, perfect in both her studies and the magical arts. However, the only reason Guest worked so hard was "for her father." She challenged everything and remained perfect because she wanted his praise and recognition. Yet, from the moment she was born until she turned 18, he never even met her eyes, only coldly pushing her away. Those days crumbled away following a certain turning point. A woman the same age as Guest, Mireille, appeared. She declared in public that she was "the Grand Duke's biological daughter." Her father believed those words completely. This was because Mireille truly resembled him, while Guest did not. Everyone was convinced she must be the real daughter. Guest managed to endure each day thanks to a man she had long held feelings for, but her life took a turn for the worse. Her father stopped looking at her entirely and poured unconditional affection only onto Mireille. All of Guest's efforts were in vain. He believed everything Mireille said, and the servants followed suit. Pitiably, Guest was framed for attempted murder by poisoning. Her death sentence was decided in rapid succession, and she was executed. And now, despite having been executed, Guest woke up in her bed in her own room. The date was one year before the execution—the morning before Mireille was set to arrive.
