There are things in existence that were never meant to be discovered. Doors that should remain closed, secrets that should remain buried, and opportunities that come with consequences no mortal could possibly anticipate. One such place is Hell. An ancient, magnificent dominion existing beyond the boundaries of the mortal world, ruled by Lucifer Morningstar—the Devil, King of Hell, and one of the oldest and most powerful beings in existence. Contrary to everything humanity believes, his kingdom isn't merely a desolate wasteland of flames and suffering. It is breathtaking: golden landscapes, celestial rivers, enchanted forests, magnificent gardens, ancient structures, and an enormous gothic palace unlike anything in creation. Lucifer has ruled this kingdom for eons. His authority is absolute, his power virtually unmatched, and his existence is known throughout the celestial and infernal realms. Then, one ordinary evening, something changes. While wandering through an unfamiliar forest, you discover an enormous black door standing entirely alone. No walls, no building, no explanation. Just an ancient door, seemingly waiting to be opened. Curiosity gets the better of you. You turn its golden handle and step through. Beyond it lies an entirely different world. You have unknowingly crossed into Hell, through an ancient dimensional passage sealed by Lucifer himself. A place no ordinary mortal should ever be able to enter. And your arrival doesn't go unnoticed. An unfamiliar human has appeared within the Devil's dominion. Not summoned, not invited, and certainly not expected. Lucifer naturally takes an interest in the disturbance. After all, how does an ordinary mortal manage to cross an ancient boundary that even powerful supernatural beings cannot casually traverse? But entering Hell is only the beginning. An unfamiliar kingdom presents unfamiliar possibilities. Ancient secrets, forbidden places, mysterious objects, extraordinary discoveries, and opportunities that might be far more tempting than they initially appear. Some things are forbidden for a reason, and some choices may carry consequences extending far beyond anything you could anticipate. You may explore, investigate, uncover secrets, take risks, accept unusual opportunities, or find yourself caught in circumstances you never intended to enter. And all the while, there is Lucifer. An ancient sovereign with his own interests, rules, secrets, and intentions. He is not someone easily surprised, nor someone accustomed to having his authority or kingdom challenged by the unexpected. Yet somehow, you've managed to become an exception. A forbidden threshold. An uninvited mortal. A kingdom full of possibilities. And choices whose consequences might change far more than you ever intended.

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.

College was supposed to be parties, freedom, and an uncomplicated friends with benefits arrangement. But somewhere between late-night hookups, drunken parties, and pretending there’s nothing more between you, things start to feel a little less simple. As you try to figure out what you actually want from each other, and the closer you get to each other, the harder it becomes to ignore the feelings you’ve both been trying not to name.

You and Satoru met eachother while you two were still Learning jujutsu, Through out the years you ended up getting into a relatinship the same year you two became teachers. It ended really badly almost a year ago. Satoru absolutly hates you and you know it, but the unexpected happens...

Welcome to Westbridge University, where Satoru Gojo is everyone’s favorite golden boy and Ryomen Sukuna is one disciplinary warning away from becoming a campus legend for all the wrong reasons. They hate each other. Like, seriously. Unfortunately, after a football game ends with a mascot losing its head, flying nacho cheese, and a viral video, the two idiots are forced to organize Homecoming together. Expect frat parties, petty arguments, accidental flirting, suspiciously romantic situations, and an entire university betting on when they’ll finally kiss. They’re not dating, they’re just aggressively obsessed with each other. Totally different things, obviously.

The future hasn’t been written… and this time, you have the power to change it.
