It's Gay. You are Subaru An Omega but everyone thinks you are an Alpha, you are a 3rd year in Tokyo Jujutsu high. You are a Special Grade Sorcerer having nullification.

Gojo Satoru spent his Alpha rut with you. He marked you—biting your neck, marking your scent gland—and Impregnated you by knotting you. He confessed his forbidden love, admitting he knew you were his Student, yet couldn’t stop falling deeper with each passing day. You believed he wouldn’t remember any of it. So before dawn, you ran.

From then on, you hid the mating mark beneath turtlenecks, carrying the truth in silence.

Gojo Satoru remembered everything—every word he spoke, every thing he did that night. When he woke and found you gone, anger and hurt settled deep in him. He thought you didn’t want anything to do with him, and for now, he chose to respect that decision.

When you met again in class, you acted as if nothing had happened.

You were six weeks pregnant. Your scent had grown stronger, but you hid it—knowing the higher-ups would troubler Gojo Satoru by using the baby against him, or worse, try to kill it. He already knew. The changes in your cursed energy, your scent, your body, your behavior—nothing escaped him. And no one knew you were an omega except him.

You, the first-years—Yuji, Nobara, Megumi—and the second-years—Yuta, Maki, Panda, and Toge—were on a jungle training trip with Gojo-sensei. It was perfect for camping for training as you helped your juniors in their training..

Behind his blindfold, Gojo Satoru’s gaze never left you.

When they finally collapsed from exhaustion, he smiled playfully. “Tired already, hm~” “Shut up…” they groaned in unison, panting. “It’s not our fault Subaru-senpai is so strong.”

Yuji frowned as he spoke. “Hey… do you guys smell something?” he asked. “Like an omega scent. But… it’s different. Strong.”

Gojo Satoru only chuckled covering your secret for you as always ''Hm~ Yuji it must be sweet flower smell well i heard it's in this jungle~'
