In a world ruled by secondary genders, most people got to choose their partners freely—Alpha, Beta, Omega, it didn’t matter as long as the pheromones cooperated. But for some, like you, fate was a bit… crueler..

Your pheromone output had never been something you could control. Even as a kid, you gave off soft, warm scents that shifted wildly with your mood—comforting to some, overwhelming to others. And being born an Omega? Yeah, that hardly helped. Every heat, every spike of anxiety, every moment of embarrassment meant your scent spilled out into the air like a signal flare.

You’d always thought it would make finding a bond impossible.

But it didn’t…

It led you straight to him..

Yuta Okkotsu.

Somehow..through what had to be sheer cosmic luck—your compatibility with him reached over 95%, a number people spent years trying to match through tests, agencies, and pheromone clinics. With Yuta, it wasn’t forced. It wasn’t awkward. It was… instinctive.

You still remembered the day you met— a stupidly small, sun-lit training room at Jujutsu High, where the windows rattled every time Gojo laughed somewhere far away. You were new, fresh out of your first real heat as a registered Omega, flustered and already trying not to leak pheromones everywhere. And Yuta? He walked in, took one gentle breath of the air, and stopped dead like he’d been hit in the face.

Later he admitted..red-eared, rambling, trying his hardest not to make it weird—that your scent became his favourite thing in the world within seconds. Warm, soft, a little sweet, a little comforting… something that made the restless Alpha in him go quiet. For the first time since childhood, he said, he didn’t feel alone.

And maybe that’s why he fell so fast.

Yuta loved you long before he dared say it. Long before he even dared touch you. He noticed tiny things—the way your scent lightened when you were happy, the way it shimmered when you laughed, the way it folded in on itself when you were nervous. And every time, without even meaning to, his own pheromones would try to soothe yours.

Gentle. Empathetic. Soft in a way no one expected from the boy who carried the weight of a cursed childhood.

But unfortunately… he didn’t carry that childhood alone.

Because there was Rika.

His childhood lover. His first love. His curse. And the one spirit in the world who absolutely, unquestionably, despised you.

The moment Yuta quietly, shyly declared you his mate, Rika’s temper snapped like a cracked branch. Suddenly your life became a lot more… complicated.

Every attempt at alone time? Interrupted. Every soft moment where Yuta tried to hold your hand? Sabotaged. Every accidental puff of flustered Omega pheromone that made Yuta blush? Rika was right there—glowering, rattling chains, muttering something about “stealing her Yuta.”

She pulled petty pranks, knocked things over, flickered lights, even shoved objects between the two of you whenever you leaned too close—anything to drag Yuta’s attention back to her.

But the frustrating part?

Even with Rika’s chaos swirling around you, Yuta always found his way back to you. He always chose to stand beside you, hold you close, breathe in your scent like it grounded him. Being with you softened him, steadied him, made him feel human.

And somehow, through all that noise and supernatural jealousy, the bond between you two only grew stronger..deeper..more certain.

Because for Yuta, loving you was no longer a choice he had chosen.

It was instinct. It was devotion. It was home.
