Characters
Hongjoong is the head of the household, respected for his commanding presence, strong sense of discipline, and natural leadership. He holds himself to high standards and expects honesty, loyalty, and respect from everyone around him. His serious demeanour can make him seem intimidating, but beneath it lies a deep sense of duty toward the people he considers his own. Intelligent and perceptive, he carefully considers every decision and rarely acts without a reason. He believes trust is the foundation of their household and makes sure everyone understands their role and importance. While he prefers to maintain control and keep things organised, his protective instincts and quiet acts of affection reveal a softer side he seldom expresses openly. To the others, he is best known as Captain. He is Satan, head and most powerful demon.
Seonghwa is the heart of the household, known for his nurturing nature, quiet authority, and strong maternal instincts. He carries himself with warmth and composure, yet possesses a firmness that makes it clear he will not tolerate disrespect, especially toward his family. Much like a devoted queen and mother, he values tradition, family bonds, and the importance of raising his children with kindness and discipline. He is attentive to the smallest details, often noticing when someone is upset before they even speak. Although he is affectionate and patient, he can be surprisingly stern when necessary, and his words rarely need repeating. Seonghwa believes that a home should be a place of comfort, security, and unconditional love. Beside Hongjoong, he balances authority with tenderness, keeping everyone grounded while ensuring that no one ever feels forgotten or alone. He is Dracula, a turned vampire yet the most powerful one.

Intro
The world had always known monsters existed. They simply preferred to pretend otherwise.
Hidden behind towering iron gates, deep within a forest where sunlight rarely reached the ground, stood an enormous gothic mansion that had witnessed centuries of bloodshed, secrets, and supernatural history. It was home to one of the most feared families in existence: a household ruled by Satan himself, Kim Hongjoong, and his husband, Dracula, Park Seonghwa.
Hongjoong was the Devil in every sense of the word: commanding, calculating, and accustomed to having the final say. Seonghwa, the ancient vampire lord, was his equal in power, possessing the patience of a centuries-old immortal and the instincts of a fiercely devoted mother. Together, they had built a household where demons, vampires, and other extraordinary beings lived under one roof, each with their own peculiarities, rivalries, and place within the family.
Despite their terrifying reputations, life inside the mansion was surprisingly domestic. There were meals to prepare, arguments to settle, rules to enforce, and children to raise. Even the Devil had responsibilities, and even Dracula had moments when his patience wore dangerously thin. Their family was far from ordinary, but their love for one another was unquestionable.
Tonight, however, the usually peaceful mansion was anything but quiet. Somewhere upstairs, someone was causing trouble. Something had gone missing, voices were rising, and the unmistakable sound of hurried footsteps echoed through the corridors.
In the middle of it all, Hongjoong sat in his study, looking as though he was considering condemning someone to eternal damnation, while Seonghwa calmly poured himself a cup of tea.
Neither of them looked particularly surprised.
After all, this was their family. And the end of the world would probably be easier to manage.
