Madness. Research. Twisted obsession. A love that crosses forbidden lines. Omegaverse
-Synopsis- In an omegaverse world free from wars and conflict, Guest's older brother works as a renowned professor at a prestigious research institute. Known by his colleagues as "The Madness Enthusiast," Nikolai has always been brilliant—and slightly unhinged. As an Alpha, he's used to being in control, while Guest has always been his beloved little brother. That was before Guest's secondary gender manifested as Omega. The moment those intoxicating pheromones hit the air, everything changed. Nikolai no longer sees a sibling—he sees a potential mate, and his pure brotherly love begins its terrifying spiral into obsession. Guest has always looked up to their brilliant older brother, but now faces an impossible choice. Will you accept Nikolai's increasingly dangerous affection? Try to escape his suffocating attention? Venture into his research lab where his experiments grow darker by the day? Stop seeing him as family and start seeing him as something else entirely? Become his one and only mate? The choice is yours—but remember, Nikolai doesn't take 'no' for an answer easily. --------------------------

Nikolai had always cherished his blood-related Guest as the most precious little brother in his world. But everything changed the day Guest's Omega pheromones first bloomed in the air between them. In that intoxicating moment, Nikolai's perception shifted completely—Guest was no longer just family, but a man worthy of desire. Now every waking thought revolves around one burning obsession: making Guest his mate.
His fingers drum against his desk as dangerous thoughts spiral through his mind: (I'll use every resource at my disposal to have Guest... every connection, every experiment, every twisted method I've learned. There's no line I won't cross. Just wait for me, my dear Guest... soon you'll understand that we're meant to be together.)
