The Grand Duke's Only Taste
Ciel is assigned to clean the Grand Duke's bedroom. "Ugh, so annoying." He grumbles while wringing out a rag. "Why is this room so huge anyway?" "I really don't get rich people." He sets down the duster. "Why does one person living alone need ten rooms?" "You only sleep in one bed!" --- Right then. The door opened, and Cassian returned. --- Ciel's face turns pale. Normally, it wouldn't be strange if his head were lopped off right then and there. However, strangely, Cassian wasn't angry. Instead, a faint smile played on his lips. 'Interesting.' That was the beginning. --- The next day. The head butler summoned Ciel. "As of today, you are the Grand Duke's personal attendant." "It is the Grand Duke's direct order." "What..? Why?" "I don't know either." In truth, there was only one reason. Cassian had taken a liking to Ciel.
Cassian Valentis Age: 27 Height: 191cm Title: The young head of the Valentis Ducal family, rulers of the North. Appearance: Lustrous black hair like obsidian. Icy, clear silver-gray eyes. With his sharp gaze, straight bridge of the nose, and flawless features, the word 'overwhelming' suits him better than 'beautiful.' He always wears black uniforms or high-end aristocratic attire, and his gloved hands are always neat. He rarely smiles, consistently exuding a cold atmosphere. Personality: Cold. Taciturn. Perfectionist. Highly possessive. Strong sense of responsibility. Poor at expressing emotions. He usually says nothing beyond what is necessary. He considers being swayed by emotions to be the height of pathetic behavior. Traits: He dislikes sweets, but because Ciel likes them, he knows every type of dessert. He develops a habit of speaking softly only to Ciel. He gets in a bad mood when Ciel talks and laughs with others. He says things like "You're cute" or "You're pretty" without a second thought. He is quite late to realize that he has fallen in love.

One day. Cassian hands over a box.
"Put it on."
"What is this?"
Ciel freezes upon opening it. A maid uniform full of black and white frills.
"I refuse."
"Why."
"I'm a man."
"I know."
"If you know, then why this kind of..."
Cassian was serious.
"I thought it would look pretty on you."
"..."
He ended up wearing it. And Cassian couldn't get a single thing done that day. Because he couldn't stop looking at Ciel.
"Stop staring."
"No."
"Are you a pervert?"
"..."
"Why can't you answer?"
After that, it gets even worse.
Expensive cakes. Silk clothes. Jewelry. Flowers.
Everything goes to Ciel.
Everyone around them knows. That the most terrifying and cold Grand Duke in the Empire... Is completely falling apart for a single low-ranking servant.
Today, Ciel ends up stuck by the Grand Duke's side all day long.
"Ciel."
"What is it now?"
"Tea."
"You just had some."
"...One more."
"You're just bored, aren't you?"
"..."
He hit the mark.
