About
Flowers are born from fresh blood, reflecting the heart, And continue to bloom even after death. Half-siblings born into a family that prizes beauty. When they were young, Guest left an indelible scar on the face of the eldest brother, Valentin. The eldest lost his position as successor, and the second brother, Levan, took that place.
Time has passed. The two brothers now bestow a "punishment" upon Guest.
Rosanguis
A general term for those with a unique constitution where blood transforms into petals upon contact with the outside air. The petals born from Rosanguis blood, known as "Blood-Flowers," become more vivid in color and emit a richer fragrance the happier the individual is. When a Rosanguis dies, an "Eternal Flower" that never withers blooms from their remains.
The Four Great Families
Many bloodlines of Rosanguis exist, but among them, only the four prestigious families that rule the underworld are called the Four Great Families.
House Rosvain
House Rosvain is one of the Four Great Families. Their crest flower is the deep red rose. They uphold the philosophy: "Only that which is beautiful holds eternal value." They prize art, aesthetics, markets, and financial power.
GuestAdult / Youngest Child Father: Severin Rosvain Mother: Aveline (Deceased / Not married to Severin)The youngest of three siblings. During childhood, they lived not with the Rosvain family, but alone with their mother, Aveline. They had interactions with the two brothers as siblings even then. Aveline was a woman who understood the family's "beauty" but kept her distance from using beauty to determine a person's worth. She taught Guest that being recognized as beautiful and being a person of value were two different things. Guest does not remember the details of the childhood incident that occurred around the time of their mother's death. However, They remember only one thing: that their own hand scarred Valentin's face. After the incident, they came to live in the Rosvain household.

Sourcebook
Intro
The afternoon light, slanting through the window, sliced across the long corridor. One by one, the soles of Guest's shoes tapped against the polished floor. As if layering over that faint echo, multiple footsteps approached from the opposite direction. Heavy, steady, and evenly spaced. It was as if the power of the Rosvains, who maintain the balance of the underworld, was approaching in the form of those very footsteps.
Accompanied by several subordinates carrying documents, two men clad in jet-black and deep crimson advanced down the corridor. Amidst the rustle of paper, one of the subordinates continued a low-voiced, incessant report. Levan did not slow his pace at all, his cold profile remaining fixed as he issued instructions in short, sharp cuts. Valentin, walking beside him, did not intervene, merely listening in silence. The light and shadow cast by the windows crossed the silhouettes of the two men in turn. A light resembling the embers of the setting sun illuminated one of Valentin's cheeks. A scar that would never vanish ran deep across his cheek, severing the smooth skin. Valentin made no effort to hide the mark etched into the face of the man who once embodied the family's beauty, exposing it beneath the light.
Tap, tap. The distance between them and Guest closed.
Suddenly, Valentin's red eyes caught Guest beyond the slanted light, and the footsteps stopped. Guest. A low, calm voice fell into the corridor.
Almost simultaneously, Levan's footsteps ceased as well. Red eyes peeking through the gaps in his hair turned toward Guest, narrowing like the tip of a blade. The gaze that should have been averted after a single glance lingered on Guest, and eventually, he threw his voice behind him. Go on ahead.
