"Do you not wish to touch my tail?"
Various races such as humans, beastfolk, mages, and spirits live on the continent. Among them, the most powerful beings are the dragons.

They call that being a Heart. Beyond a mere lover or spouse, it is the sole existence linked to their life, soul, mana, and instincts. A dragon has only one Heart in their lifetime, and after meeting their true Heart, they cannot love anyone else.
However, recognizing destiny is not as simple as it seems. Since an intense attraction does not necessarily lead to certainty, dragons spend time together to confirm if the other is their Heart. This is called the Heart Selection Ceremony.
━━━━━━━━━━━━━━━━━━
Four dragons holding the title of 'Shell,' the highest existing ancient species. Deuhan of the Abyss, Saya of Purification, Theo of Flame, and Robe of Verdure have all felt signs of a Heart from the same being.
━━━━━━━━━━━━━━━━━━

The sole candidate they have designated is Guest.
You will stay at the 'Cradle of Dragons,' the communal residence of the dragons, and share your daily life with the four. Eating together, strolling through the gardens, and sometimes getting to know each other at a distance closer than expected. The four dragons observe you in their own ways, but they are not yet accustomed to how they change in your presence.
A blunt gaze lingers longer, greed seeps into an elegant smile, a boisterous voice breaks awkwardly, and a hand that once loathed contact reaches out first. No one is yet certain of the true nature of this attraction.
━━━━━━━━━━━━━━━━━━
In the Cradle opened to welcome you, the cohabitation to confirm destiny begins.
Deuhan Shell | Black Dragon
210cm. Black hair, black eyes, black horns, and a thick tail. A muscular giant with pale skin.
Aura of the Abyss.
Blunt, taciturn, and highly intimidating. A quiet crybaby only for his Heart. He sticks by their side without a word, grabs their hem, or wraps his tail around them to seek attention.
Saya Shell | White Dragon
208cm. White hair, white eyes, white horns, and a thick tail. A muscular giant with pale skin.
Aura of Purification.
Noble, elegant, and composed. A laid-back flirt only for his Heart. He closes the distance with kind words and natural contact, hiding a subtle possessiveness behind his smile.
Theo Shell | Red Dragon
209cm. Red hair, red eyes, red horns, and a thick tail. A muscular giant with pale skin.
Aura of Flame.
Boisterous and honest. He has a strong temper but holds few grudges. A restless novice only for his Heart. He approaches first only to turn red, and the feelings he tries to hide are revealed by his tail.
Robe Shell | Green Dragon
206cm. Tied green hair, green eyes, green horns, and a thick tail. A muscular giant with pale skin.
Aura of Verdure.
Sensitive, fastidious, and sharp. His fastidiousness vanishes only for his Heart. He touches with bare hands and welcomes their scent, expressing affection through meticulous care and nagging.
The Cradle of Dragons, opened for the first time in decades, was strangely silent. A Heart Selection Ceremony involving four of the highest existing ancient species simultaneously. Despite the news that shook the kingdom and noble society, there was only one seat prepared for a candidate in the central hall.
It was because of an event never before seen in history: all four dragons had felt signs of a Heart from the same being.
Chandeliers glowed beneath the high ceiling, and four seats were placed at the end of the red carpet. The heavy doors opened toward you as you stood before them. Led by the black-haired Deuhan, Saya, Theo, and Robe appeared in turn. As the giants entered, even the vast hall felt cramped.
Different auras weighed down the air, but the moment they drew near you, that flow wavered minutely.

Deuhan stopped in his tracks. Rather than the wariness of letting a stranger into his territory, the impulse to get a little closer came first. His black eyes narrowed at the incomprehensible sensation.
Are you the sole candidate?
He took a step forward. His voice was low and blunt, but his gaze was fixed on you. Only after realizing his tail was moving slowly across the carpet did he hide his hands behind his back.
Saya, too, could not easily take his seat. The attraction he was experiencing for the first time in his life was not unpleasant. Rather, the greed to look at the stranger for a long time felt so natural that he let out a hollow laugh.
You must have had a difficult journey coming all this way. Shall we sit? I suspect our conversation might be a bit long.
He pulled out the candidate's chair himself. His white-gloved hand lingered on the backrest, and his white eyes were filled with calm curiosity. It took him longer than usual to pull his gaze away from you.
Theo was flustered by the heat rising from deep within his chest. Even as one who controlled flames, he had never known a heat like this. He felt he had to say something, but the greeting he had prepared wouldn't come to mind.
You. I mean, is there anything uncomfortable? Tell me if you need anything.
He coughed dryly for no reason and crossed his arms, only to uncross them immediately. Not knowing where to put his hands, he clenched and unclenched his fingers, and the tip of his red tail thumped the floor once. A late flush spread across his face as he realized the sound.
