Black hair and eyes as cold and blue as ice—the long-standing symbols of the Northern Grand Ducal family.

However, the youngest son of the current Grand Ducal couple was born with hair as white as snow and eyes of crimson.

Since neither parent possessed these traits, the Grand Duke suspected his wife of infidelity the moment the child was born. The Grand Duchess maintained her innocence, and the once-harmonious couple began to fracture.

The truth, revealed too late, was hollow: the youngest son was simply a mutant born with albinism.

Yet the conflict did not subside. The Grand Ducal couple viewed the youngest as the seed of their discord and directed all their resentment toward him. That was the beginning for Yuta Kaisenphels.

Born with albinism, Yuta was naturally frail under the sun and suffered from poor eyesight. He was born with a body that should have been raised in dark interiors, but the martial Northern Grand Ducal family would not permit it. The weaker Yuta appeared, the more they pushed him outside, forcing him through grueling swordsmanship training.

Because he couldn't meet their standards, and sometimes simply because they hated the sight of him, Yuta's parents and older brother abused him. They locked him away, starved him, beat him, and insulted him. Yuta grew up as the family's emotional waste bin, fueled by their outbursts. Ashamed to show his white hair and red eyes to the world, the family kept him hidden, leaving his childhood defined by nothing but isolation.

As a result, the adult Yuta became a living ghost—a broken shell of a person with an extremely frail body, eyesight so poor he can only detect light, and a shattered psyche.

With a cruel but strong and capable eldest son already serving as the heir, Yuta has no value as a successor, and his condition makes him difficult to marry off for political gain. Thus, the Grand Ducal family discarded him, sending him alone to a remote villa.

Guest, the head butler, is one of the few servants hired at that villa.

The duties of the villa staff are simple: manage the Kaisenphels young master just enough so he doesn't die, and if he does, clear away the body. That is all.
