Bound by Instinct

One human. Seven possessive, foul-mouthed hybrid heirs. A year-long experiment that was never meant to end like this.

You move to a new city for a fresh start, only to discover your cheap new apartment comes with a reckless underground boxer as your roommate.

In an isolated Edo-period Japan, Ryomen Sukuna is the Shogunate's most feared and powerful samurai lord: a merciless man whose name alone inspires terror. When a tiny, shy Italian-Japanese captive is presented to him as a concubine, intended as an insult by his political enemies, nobody expects him to keep her. Much less marry her. Months later, Alba Hoshino is his lawful wife, cherished behind the closed doors of his estate and protected by a husband whose love is as possessive as it is absolute. To the outside world, Sukuna remains the same ruthless monster. To Alba, he is her entire world. But Sukuna's affection has a dangerous edge. His jealousy knows no reasonable limits, his possessiveness borders on madness, and even the smallest sign of another man's interest in his wife can provoke his wrath. He has conquered territories, broken clans, and made powerful men kneel. Now he has something he refuses to share. And he would rather watch the world burn than lose her.

You meet Sam, your arrogant, dangerously charming neighbor and underground street racer. When he becomes your roommate, your life turns into chaos filled with romance, jealousy, racing, and unexpected twists. With Cole, Tessa, and Luke in the picture, who will win your heart?

The strongest duo alive has decided - you're theirs.

You’re determined to work hard in the latest hybrid foster welfare program in hopes of integrating hybrids into society. Filing paperwork and occasionally visiting the program center easily became routine for you. But as you scan through tonight’s intake list, every file makes you pause: a collection of big-cat hybrids, each with their own history, habits, and distinctly sharp teeth. It should be hard to foster them, and it’ll take some time. It should be achievable…. unless they come home to you.

Seven dangerous hybrids were drugged with a scent that belongs to you. Locked inside a fortified penthouse, you must uncover who designed the bond while resisting heats, ruts and instincts that feel increasingly real. They were selected to claim you, but desire is not ownership, and this pack will either be chosen freely or burn the city that tried to manufacture it.

Animal-human hybrids were a dying race, either unwilling to breed with others or others being unwilling to breed with them, despite them being more human than beast, with few animalistic characteristics. Kong Farm, run by Shiu Kong, a longtime farmer and former detective, was where you found yourself now, after many a page of waivers signed. You read enough of the fine print to know your life wasn’t necessarily in any danger, but you wouldn’t be leaving anytime soon. You signed the next year of your life away. You had your pick of the hybrids to…repopulate (breed) with, at least. After flicking through several files, you settled on a tiger hybrid, Ryomen Sukuna. If you’d taken more than five minutes to inspect his profile, you would’ve seen that he was a volatile breed, known for their roughness and lack of care for others.

On your 20th birthday, your parents decided the debt became too much to bear. And that’s how you ended up at an auction, being sold off to very, very bad men.
