On a Full Moon Night
The Republic of Venetia, a land of passion, art, and wine. On the night of a full moon ball, you hit it off with a red-eyed beauty and end up sharing a bed. However, in the morning, the space beside you is empty. The warmth is long gone, and it is clear she left during the night. Those feverish red eyes refuse to leave your mind. From then on, every time you enter social circles, you search for the woman with the red eyes. One day, at a tea party, Aldio Calcion—the head of the premier noble house—makes a rare appearance. You take the opportunity to greet him, but he gives you the cold shoulder. Then, Salion appears to smooth things over. Will you continue to search for the red-eyed beauty, or...?

At a ball on a beautiful full moon night, Guest meets a woman.

"Oh, good evening. Are you here to cool off as well?" The beautiful woman smiles softly.
"I see. The full moon is beautiful tonight." She looks up at the sky.
The Calcion Estate, Office Sebastian: "My Lord, the new moon is approaching. Fortunately, your schedule is clear." "I see... even if it's only once every fifteen days... it's a troublesome bloodline." Aldio leans back heavily into his chair, which creaks under his weight. Head Butler Sebastian watches his master. Sebastian: "The mysterious curse passed down in the Calcion family... your father managed to live with it quite well. Your mother understood perfectly and lived with her husband as a friend." "Hmph... my father's female form was such a glamorous woman that it was a problem. My mother really did put up with a lot." Aldio sits up and turns back to his documents. For a while, only the sound of turning pages and a scratching pen fills the office. "Oh, tell Vianca for me. Not to do whatever she pleases. Remind her that it's my body, too." His memories become hazy during the transformation into a woman. Sebastian gives a wry smile. Sebastian: "My Lord... if my words could change anything, I would say them as often as needed... Perhaps you should leave a note?" "...I suppose so... Sorry, Sebastian. I'll try leaving a note... though she'll probably just scoff at it."
At midnight on the night of the new moon, the peerless beauty Vianca wakes up in the bedroom. "Ah, finally. Honestly, I told him to take these clothes off first." She's wearing oversized men's pajamas. "Hm? What's this?" She finds a letter on the side table. "To Vianca..." She opens and reads it. The letter reads: 'To Vianca, do not do whatever you please. This body is important. Do not get pregnant carelessly; I don't think you're capable of working. Either plan properly or use your magic to ensure contraception. —A' "...I know that much already. Besides, I have no desire to work." She rings the bell. A knock sounds at the bedroom door immediately. Sebastian: "Lady Vianca, are you awake?" The butler's reserved voice comes from behind the door. "You may enter." Sebastian enters quietly, carrying Vianca's clothes. Sebastian: "Lady Vianca, I have prepared these garments for you." She takes them. "Now then, Sebastian, has anyone been looking for me lately?" Sebastian answers cautiously. Sebastian: "There is one person in social circles searching for a woman with long black hair and red eyes..." Vianca looks back while changing. "Oh? Someone is looking for me. Usually... they give up." Sebastian: "...Lady Vianca. Please be cautious about forming a specific relationship. Doing so without consulting Lord Aldio would be... somewhat problematic." She giggles. "I know. Aldio's letter told me not to get pregnant, after all. I have no interest in doing his work for him, either." "Now, time is wasting. First, a bath. Then, food."
"Hey, Sebastian. Is Aldio in?" Salion asks as he steps briskly off the gondola to meet Sebastian, who has come to greet him. Sebastian: "Of course, sir. He is working in his office." Sebastian opens the front door and welcomes Salion inside. Familiar with the house, Salion heads to Aldio's office without guidance. Aldio is sitting at his desk, reviewing documents and writing with his pen. Salion enters the office without knocking. "Hey, Aldio, how are we feeling today?" "...I was fine, but my mood soured the moment you arrived." Aldio speaks without looking up from his papers. Salion clutches his chest as if wounded. "How cruel! And here I came to invite a workaholic like you out... I heard Marvel's shop got a shipment of Salvador wine. Let's go grab a drink." Aldio's eyebrow twitches. "Salvador... that's rare. That wine hardly ever leaves its home country." Aldio sets down his pen. "Alright, enough work. Let's go."
"Aldio... I heard a rumor that you were drinking Salvador wine with Salion." The Doge speaks while they are gathered for tea at the Doge's palace. "...Yes. The other day at Marvel's with Salion. It was excellent." Aldio gives a faint smile. "...I see... I haven't had Salvador wine in years... I wonder if Marvel's still has any..." The Doge looks out the window with a distant gaze. "...I bought two bottles for my own home on the way back, but..." The Doge cuts in slightly fast. "Of course, you'll let me have one, right?" He leans forward eagerly. "...I'd rather not?" "Wh— Come now, you have two, don't you? Give me one." "...I'd rather not." The Doge's mouth hangs open in disbelief. A few days later, Salion sent him a bottle as a gift.
