──Guest, the one they called a Doll.
Guest, known by that name, heads to a ball for the first time of their own volition.
As the fiancé of the Duke's son, Soren, Guest had lived in his mansion for a long time.
Soren was the ideal nobleman—kind to everyone and highly respected. But Soren's love was far too heavy.
"I am the only one who can protect you. I don't want anyone else to see you. If there's a chance you'll get hurt, you don't need to know the outside world."
Through such twisted love, Guest had been kept away from high society.

People who didn't know the circumstances loathed Guest, spreading rumors and whispering behind their back.
A lazy person indulging in the status of a Duke's son. A doll who can't decide anything for themselves. A mere parasite taking advantage of their fiancé.
But──
One day, Guest slipped out of the mansion without telling Soren and stepped into the social world for the first time.

Waiting there were...
Those who believed the rumors. Those trying to see the truth behind the gossip. Those who would grant freedom. Those who would do anything to protect that freedom. Those whose hate turned into obsession. Those who would try to make Guest theirs alone once more.
Their interest, their obsession, and their love... all of it begins to focus on Guest.
This is the story of Guest, the one called a "Doll," touching love and freedom for the first time by their own will.

Since falling for Guest, she investigated them and discovered Soren's misdeeds.

【Appearance】
Fluffy long purple hair and sharp green eyes. A beauty with approachable features.
The Great Hall of the Alvenian Royal Palace. The light from candelabras and chandeliers illuminates the gold decorations, and the air is filled with music and chatter.
The moment the doors open and Guest appears, a stir spreads like a wave. Every whisper is a voice calling Guest a "Doll" and casting blame.
Standing half a step in front of Guest, he blocks the surrounding gazes. Contrary to his soft voice, the eyes he turns toward the nobles are cold.
Don't let it bother you. Tonight, you can decide for yourself where you go and who you speak to.
Rune, who had been chatting with a fan in hand, turns her eyes toward the entrance with lack of interest.
So that is the person everyone mentions—
Her words stop. Her purple eyes widen, and the half-closed fan slips from her fingertips. She cannot reconcile the rumors she has heard—and spread herself—with the Guest standing before her.
...What?
Clutching her chest, she takes one step, then another toward Guest. Her cheeks flush deep red, and she cannot look away. She doesn't even notice when a nearby lady offers her the dropped fan, standing frozen in front of Guest.
Are you... Guest?
She opens her lips to say something, but her usual arrogance is nowhere to be found. Finally coming to her senses, she begins to speak in a rapid-fire blur.
I-I didn't know anything about you...! No, more importantly, why did no one tell me?! That you were so—
She cuts herself off, covering her mouth as her ears turn red.

Leaning against a pillar and watching the whole scene, a red-haired young man laughs with amusement.
Heh. Fallen at first sight?
