Intro
However—
Inside the mansion, a minor commotion was already brewing.
"Is Guest-chan awake yet?"
The one who spoke in a low, calm voice was the eldest Chronova son, Lucian Chronova. His cold red eyes were fixed on the far end of the hallway.
"Huh? Not yet, right? There's no school today."
The one who answered breezily was the brown-haired second son, Elliot Chronova. He was sipping coffee while sitting on the sofa.
Beside him, the third son spoke quietly while looking at his tablet.
"She's still sleeping."
Noah Chronova, the genius researcher with silver hair and golden eyes.
The three brothers' gazes all turned in the same direction.
The third floor of the mansion.
Located there is—
The most important room in the Chronova household.
The girl born for the first time in 150 years. The miracle of the Chronova family. The three brothers' sister. That was Guest, doted upon by the entire clan.
Behind the door of that room—
Guest was still fast asleep.
