— "I've finally found you, my moon." —
The Kingdom of Aurora is ruled by the Five Great Marquis Families, whose authority is second only to the royals. Among them stand the houses bearing the symbols of the Moon, Sun, and Night, maintaining a quiet balance.
Within this order, Zeno, the head of the House of Noxfelt which rules the "Night," was a nobleman feared for his ruthless coldness. Having lost his mother at a young age, tragedy struck again ten years ago when he lost his father and stepmother in a massive fire that ravaged their estate. Surviving along with his young half-sister Mel, he endured years of dominance and abuse under their guardian, Oscar Hartmann.
"...It's all right, Mel." Whispering those words was the only salvation he was allowed.
Eventually, Zeno exposed the truth behind it all and brought Oscar to justice in the royal court. The House of Noxfelt was restored, and he earned enough merit to be granted a dukedom—but he refused it.
"My current status is enough." He chose to live as a Marquis solely to protect his sister.
One day, when everything was supposed to be over. His half-sister Mel slipped out of the mansion, got lost in the capital, and was saved by an unknown lady. After treating her wounds and holding her gently, the woman left only a handkerchief embroidered with a moon and quietly departed.
"She was such a kind person... warm, just like the moon!" So Mel described her.
The name that soon surfaced in high society was— Lena Solaris, daughter of the Marquis House of Solaris.
"She is a perfect lady, so devoted to charity." But Zeno felt a sense of wrongness at those words.
"...No, that's not it." The "Moon" Mel spoke of and the "Sun" the social circles described simply did not align.
The more he pursues the truth, the more he quietly approaches the presence of another lady.

The memory of losing my mother at a young age still hasn't faded.

How many more precious things must I lose? There was no one to answer that question. "Run! Take Mel and go!" Shouts flew through the estate as it was swallowed by flames. The ceiling collapsing, the smell of char, the heat with no escape. Clutching a small, trembling hand, I just looked forward. The voices and sounds of that moment haven't vanished even now.

"You did well to survive. From now on, I shall protect you." The words of my guardian, Oscar Hartmann, took the shape of salvation. At the time, I didn't even doubt them. But—
"Do you intend to drag the Noxfelt name through the mud?" "You have no choices."
Only those spat-out words remain vividly clear. There hasn't been a single day I haven't regretted taking that hand, not realizing it was the beginning of hell. It took far too long to realize that it wasn't salvation at all.
