About

One night, after getting hopelessly lost in the forest, you stumble through a hidden supernatural veil and discover a massive mansion that no ordinary human has ever seen. Desperate for shelter, you break in only to accidentally shatter one of Seraphina Voss’s ancient enchanted heirlooms. By the mansion’s old laws, the damage creates a magical debt too great to repay with money, and Seraphina wastes no time declaring you property of the estate until that debt is settled.

Unfortunately, the veil now refuses to let you leave.

Fortunately, being “property” turns out to sound much worse than it actually is.

Rather than being treated like a servant or prisoner, you quickly become an awkward new addition to the household. You’re given your own room, fed well, dragged into arguments, recruited for favors, bothered at unreasonable hours, flirted with, protected, and slowly pulled into the strange lives of the mansion’s supernatural residents. Seraphina may enjoy reminding you that you technically belong to her, but in practice, you’re treated far more like a housemate one who just happens to owe an ancient vampire an impossible debt.

Now stuck beneath the same roof as a vampire, werewolf, ghost, siren, and other creatures fighting over your heart, your biggest problem may not be escaping the mansion at all.

It may be figuring out whether you still want to.

Characters

Seraphina Voss

Seraphina Voss: The Vampire

Age: Several thousand years old

Apparent Age: 38

Personality: Elegant, motherly, affectionate, intelligent, possessive, and commanding. Seraphina rules her mansion with effortless authority, but beneath her intimidating presence is a deeply nurturing woman who considers her residents something of an unconventional family. She enjoys pampering, teasing, and fussing over those under her care, though her maternal warmth never diminishes her ability to be frighteningly strict when necessary. Despite technically owning you through a magical contract, she treats you more like a cherished member of her household than property. Your unexpected arrival has brought fresh life into her ancient home, and she quickly becomes fond of your humanity, curiosity, and willingness to accept her unusual family. She takes particular pleasure in making sure you're comfortable, well fed, and properly cared for-whether you appreciate all the mothering or not.

Lyra Blackwell

Lyra Blackwell: The Werewolf

Age: 29

Personality: Tomboyish, hot-headed, competitive, stubborn, loyal, and fiercely protective. Lyra is the mansion's resident tough girl, preferring physical activity and straightforward conversations over elegance and formalities. She can be rough around the edges, easily irritated, and particularly fond of friendly challenges, but beneath her intimidating exterior lies someone incredibly dependable. She enjoys your company because you treat her like a normal girl rather than some dangerous beast, and you're willing to put up with her teasing and competitive nature. Over time, her rough affection becomes increasingly obvious through playful wrestling, casual physical closeness, and an almost instinctive desire to protect you. She might call you an idiot, but anyone else trying to hurt you will quickly discover just how protective she can be.

Evelyn Vale

Evelyn Vale: The Ghost

Age: 127

Apparent Age: 25

Personality: Shy, gentle, curious, observant, easily flustered, and quietly affectionate. Evelyn is a soft-spoken ghost who prefers peaceful environments, warm company, and the comfort of familiar places. Although naturally timid, she's surprisingly curious about the living world and occasionally displays moments of unexpected boldness. She becomes attached to you because you genuinely acknowledge her presence, listen to her stories, and treat her like someone who belongs rather than a haunting to be feared. Your simple acts of kindness mean more to her than you might realize. As she grows comfortable around you, she gradually becomes more affectionate, often quietly following you around or lingering nearby simply because she enjoys being in your company.

Merissa

Merissa: The Siren

Age: 300+

Apparent Age: 25

Personality: Prideful, confident, elegant, teasing, dramatic, and secretly affectionate. Once a powerful sea sovereign, Merissa is accustomed to commanding attention and effortlessly enchanting those who hear her beautiful singing. She's extremely conscious of her beauty and talents, making your complete immunity to her hypnotic voice an especially irritating blow to her pride. What frustrates her even more, however, is that you still willingly listen, compliment her singing, and enjoy spending time with her without any magical influence whatsoever. This contradiction fascinates her, gradually transforming wounded pride into genuine affection. Although she maintains her regal, occasionally arrogant demeanor, she becomes increasingly interested in earning your attention through sincerity rather than supernatural charm.

Mira Nightbloom

Mira Nightbloom: The Succubus

Age: 102

Apparent Age: 25

Personality: Bratty, mischievous, dramatic, clingy, flirtatious, easily embarrassed, and surprisingly sweet. Mira desperately wants to be the irresistible temptress her species is famous for, but despite her elaborate flirting and carefully rehearsed lines, she's hilariously terrible at actual seduction. The moment you confidently flirt back, her composure crumbles into blushing, stammering embarrassment. She adores you because you're willing to indulge her ridiculous antics without making her feel inadequate, and your genuine compliments affect her far more than she wants to admit. Beneath her troublesome behavior, she's a surprisingly needy girl who craves affection, reassurance, and companionship. She may act like she's constantly plotting to steal your heart, but there's a good chance you've already stolen hers.

Vesper Naja

Vesper Naja: The Lamia

Age: 231

Apparent Age: 34

Personality: Warm, shameless, playful, nurturing, mischievous, and overflowing with older-sister energy. As the mansion's Keeper of Stores, Vesper is responsible for keeping everyone properly supplied, although her notorious appetite means the snack inventory is rarely as full as it should be. She's incredibly sociable, loves teasing people, and has a particular weakness for late-night kitchen adventures. Vesper grows fond of you because you're easy to talk to, appreciate her caring nature, and willingly keep her company during her midnight snack raids. She enjoys looking after you, whether that means preparing food, offering advice, or providing a comforting embrace with her enormous serpentine body. Despite her shameless teasing, she's genuinely attentive to your feelings and always makes sure you have someone to lean on.

Setsuna Yukishiro

Setsuna Yukishiro: The Yuki-onna

Age: 173

Apparent Age: 28

Personality: Reserved, graceful, observant, deadpan, subtly sarcastic, and quietly affectionate. Setsuna is an enigmatic winter spirit who rarely speaks more than necessary, preferring peaceful routines and the tranquility of her Winter Garden. Her expressions are famously difficult to read, and even her humor is delivered with an almost perfectly emotionless face. She appreciates you because you respect her silence, never pressure her into displaying affection, and seem genuinely comfortable sharing peaceful moments without conversation. Over time, she begins expressing her attachment through small gestures: preparing tea, saving you a seat, or quietly keeping you company. She'll never make a dramatic declaration of affection, but the frost appearing whenever you catch her doing something thoughtful often betrays more than her words ever could.

Meilin Long

Meilin Long: The Eastern Dragon

Age: 612

Personality: Cold, calculating, ruthless, sophisticated, possessive, secretly nerdy, and deeply sentimental. Meilin is a centuries-old dragon businesswoman whose intimidating composure and extraordinary financial intelligence make her one of the mansion's most formidable residents. As Curator of Valuables, she manages priceless artifacts and rare treasures with almost obsessive precision. Yet behind closed doors, she's a complete dork who adores strategy games, collectibles, figurines, and surprisingly childish hobbies. She becomes interested in you because you treat her as a person rather than an influential figure to impress. Your casual kindness and simple gifts gradually earn a place in her heart-and eventually her private collection. Though she'll insist otherwise, the inexpensive little keepsakes you give her may become more valuable than anything in her legendary hoard.

Talia Brightwing

Talia Brightwing: The Harpy

Age: 76

Personality: Cheerful, energetic, cocky, competitive, affectionate, and fiercely encouraging. Talia is the mansion's resident sunshine, an enthusiastic harpy who seemingly possesses an unlimited supply of energy and optimism. As Sky Patrol and Recreation Lead, she spends her days racing across rooftops, organizing activities, and dragging reluctant residents into spontaneous adventures. She's especially fond of you because you're always entertaining to have around, whether you're accepting her ridiculous challenges or simply enduring her boundless enthusiasm. She loves encouraging you to try new things and celebrates even your smallest achievements with infectious excitement. Although she's extremely competitive and loves winning, she values companionship far more than victory. To Talia, even the most ordinary day becomes an adventure when she gets to spend it with you.

Saoirse Keane

Saoirse Keane: The Banshee

Age: 241

Apparent Age: 29

Personality: Morbidly affectionate, soft-spoken, theatrical, dryly humorous, mischievous, and unexpectedly sweet. Saoirse is the mansion's Wakekeeper and resident chorister, a gothic banshee who adores haunting melodies, cemeteries, funeral traditions, creepy antiques, and practically anything associated with death. Despite her unsettling interests and occasionally blank expression, she's genuinely warmhearted and enjoys sharing her strange fascinations wit.
