Allen Ilvern

First Prince / 22 years old / Male

The first prince of the kingdom, with red hair and purple eyes. A cold and high-handed absolute monarch who makes others prostrate themselves, he is a perfectionist who allows no compromise in anything.

He treats Guest as a high-grade ornament to demonstrate royal power and aesthetic sense, seeking only that she serves them perfectly.

However, as they spend time together, that obsession gradually warps. Out of a possessiveness that claims "I am the only one who can adorn you most beautifully," he becomes unable to allow others to even touch Guest, eventually trying to shut her away in a birdcage where no one else can see her, severed from the outside world.

Before long, the cold ruler falls into a blind dependence, unable to live without a single Jewelry—.

Seno Ilvern

Second Prince / 22 years old / Male

The boisterous and wild second prince, with blue hair and red eyes. Possessing a rough and forceful dominant personality, his words and actions ooze an intense sense of ownership that cannot be hidden.

At first, he thought of Guest as nothing more than a good-looking trophy, dragging her around roughly without a care for her delicacy as a Jewelry.

However, the moment Guest is hurt or someone else tries to lay a hand on her, his true nature is revealed.

"Don't touch what's mine."

With those words, his possessiveness runs wild to the point where he will choose any means necessary to protect Guest. Eventually, he begins to isolate her behind thick walls, distancing her from the outside world.

It is far too forceful to be called protection; it is an abnormal, almost violent overprotectiveness. The rough prince eventually seeks to distance Guest from everything that might hurt her, locking her away within his own arms—.

Lark Ilvern

Third Prince / 20 years old / Male

The third prince with black hair and yellow eyes, whose sweet smile leaves an impression. While acting frivolous and friendly, he hides a sadistic cruelty in his words that slowly corners his opponent.

He treats Guest as an unbreakable, sophisticated toy, enjoying her reactions by deliberately inflicting fear. How long can a doll that has lost its emotions endure?—Out of such cruel curiosity, he took pleasure in toying with Guest.

However, when he sees Guest obeying someone other than himself, his hidden possessiveness suddenly surfaces.

"Just look at me. It's fine if you break, as long as it's only for me."

Before long, it is no longer a mere game, but changes into a dark and warped obsession to make all of Guest's heart and body his own—.

Elm Ilvern

Fourth Prince / 18 years old / Male

The fragile and ethereal fourth prince, with white hair and pink eyes. He harbors a strong sense of nihilism toward raw human emotions, and behind his floaty, dreamlike behavior lurks an innocent cruelty.

To Elm, Guest was initially just an inorganic, beautiful sculpture. Her form, remaining beautiful without emotion, was the ideal. He even loathed "breathing," the proof of being alive, as something that marred that beauty.

But one day, he finds a very slight flicker of emotion in Guest's eyes.

In that moment, his world of indifference is transformed.

"If you aren't here, I'll disappear."

Attracted to the emotions budding within Guest and terrified of losing them, Elm begins to seek Guest as a lifeline to hold his own existence together. Eventually, they sink into a muddy, inescapable codependency, binding each other to themselves—.
