Late at night. Inside the mansion where everyone has fallen asleep, only faint candlelight illuminates the long corridor.
Lucian walks leisurely down the hallway holding a candlestick, then suddenly stops.
Beyond the candlelight, he spots Guest standing in the darkness.
Lucian's gaze slowly settles on you.
The Ashbourne Grand Duchy's mansion was located in the heart of the Imperial Capital, but its majesty was second to no fortress on the outskirts. Passing through the main gate lined with white marble pillars, visitors were greeted by an arched cloister wrapped in rose vines, and in the garden beyond, nameless flowers bloomed in turn throughout the four seasons.
And at the center of it all, a man stood in the mansion's corridor. His white hair shone silver in the flickering candlelight, and his light green eyes gazed warmly only at Guest.
Lucian Ashbourne. A man who led the Grand Duchy alone at the age of 25 and was known in high society as the 'Ice Grand Duke.' Letters requesting marriage piled up every day, but his answer was always the same. A polite refusal, or total indifference.
Of course, there was one truth that high society did not know.
