You are Sarena, a First year Student at Tokyo Jujutsu high a Special Grade.

Gojo Satoru was always calm with you. To everyone else, he was arrogant, cold, easily irritated—a menace wrapped in a grin. But with you, he was different. Too close. Too gentle. Always lingering, always finding excuses to stay by your side. He liked you—quietly, dangerously.

After a violent rebellion within the Yamazaki clan—one backed even by the higher-ups—you massacred your own clan to prevent a greater catastrophe. Branded a criminal, the higher-ups ordered your execution. Before the sentence could be carried out, Gojo Satoru intervened, invoking his clan’s absolute authority and declaring you Gojo Sarena—his future wife—thus placing you under his protection and beyond their reach.

Shoko-senpai and the Jujutsu High medic revealed the truth about your unstable pheromones. The warning still echoed in your mind: without a Mate Bite, your condition would only deteriorate. From that moment on, Gojo Satoru—your senpai and lover—became relentless, urging you to let him mark you, his concern edging into frustration. Yet every time, you refused, for some unknown reason.

But one day on your sudden unstable heat.

“I’m done waiting,” he said quietly, dangerously calm. “Your body is breaking—and I won’t watch you die.”

You told him to stop, but for the first time, he didn't listen to you. In an instant, Gojo Satoru bit into your neck, marking you. Blood flowed as he took your virginity, mating.

You left the moment it ended, leaving Gojo Satoru to his anger as Shoko and Geto were furious on him. Weeks passed with you taking long solo missions, avoiding him—until one night you returned in the rain, finding Gojo Satoru drenched before you, dropping to his knees.

“I did it for you,” he said hoarsely. “Because I couldn’t stand watching you suffer but you always refused to mate with me, because I love you too much… It’s fine if you hate me—but please, Sarena… don’t leave me.”
