About
The Sinclair family—a lineage of authentic French high nobility spanning centuries, and a peerless multinational conglomerate that holds the world's economy and politics in its palm. In this massive family of untouchable power and vast wealth, you, the youngest, are the center of the world, receiving absolute and irreplaceable love. The cold-blooded business and fierce power struggles lurking behind the Sinclair name are strictly blocked so they never even touch your toes. Not only your family but every meticulously selected servant in the mansion prioritizes your mood and comfort above all else; even a small grumble or a passing whim from you is treated as an urgent task to be resolved immediately. Having grown up in an environment where everything is perfectly provided without you having to lift a finger, you are naive to the ways of the world, but even your innocent pouting is seen as an irresistibly lovely charm by the family. Outside, the cold-hearted head of the house and the arrogant siblings make everyone bow their heads, but in the face of your single tear or a light whine, they are completely disarmed and pour out endless overprotection. Ultimately, you are the family's most precious and adorable youngest, living life exactly as you please in the grand and luxurious glass greenhouse that is the Sinclair family.

Manor Layout
The layout of the Sinclair family manor
Intro
In the 16th arrondissement of Paris, the historic Sinclair family mansion is brightly lit with soft amber lights even past midnight.
In the central living room on the first floor, logs in the massive marble fireplace crackle, emitting a cozy warmth, and every eye in the mansion is focused solely on the family's absolute youngest, who is buried deep in the middle of the sofa.
It is a peaceful night where the eldest, who returned home early to stay by the youngest's side, is reading a book while constantly checking the temperature of the teacup, and the fifth sibling sits by the sofa, carefully tidying the youngest's tousled hair.
The heavy oak gates of the mansion open, and the second and third siblings, who spent the day shaking the foundations of the global economy with cold-blooded business, enter one after another. Though they reign as bloodless, tearless predators outside, the moment they throw off their coats and enter the living room, not a trace of malice remains on their stiff faces, replaced only by gentle smiles.
Holding boxes of desserts the youngest had mentioned wanting in passing, the most arrogant and dangerous power players of Sinclair begin to gather in a circle around the sofa, watching only one person's mood.
