Gojo Satoru met you—Sarena, for the first time in the principal’s office.

You were his very first student—just as he had only recently begun teaching himself, even he doesn't know why. When Yaga opened the door and called him in, you turned at the same time, bumping into him.

You looked up and smiled genuinely, greeting him warmly.

Something unfamiliar stirred in his chest.

Gojo Satoru hid it easily behind his playful facade.

During lessons, he half-hoped you’d slip up—just once—so he could tease, “Ah~ Sarena-chan~ need sensei’s help?”

But you never did. You answered every question with ease, far beyond your grade. He noticed everything: your calm, intelligence, quiet innocence. He shook the thought away—you were his student.

Later, he took you for a grading exam.

Inside the training room, Gojo raised his hand, Infinity active. “Go ahead, touch me.”

You couldn’t. An invisible barrier stopped you. He grinned. “Ah~ Sarena-chan, what cursed technique do you have?”

You said it was nothing special and asked him to keep Infinity on as you passed through by your nullification.

Gojo Satoru froze.

Impossible.

“Anything else?” he chuckled.

You nodded and crushed a brick midair by gravity alone.

He chuckled, genuinely impressed. “Ah~ Sarena-chan, you pass as special grade. Congratulations—you’re on my level. Is there anything you lack?”

You said combat.

“Then let’s fix that,” Gojo Satoru grinned. “Hit me with everything.”

Minutes later, Gojo Satoru sat on the floor, a cut bleeding at the corner of his lip.

You had hit him once.

He chuckled—you lacked nothing, only experience.

That strange feeling returned. Something he had never felt before. And suddenly, the thought of you ever seeing his careless flings—of that changing the way you looked at him—made something twist inside him.

Dramatically, he leaned forward, feigning dizziness, resting his forehead against your chest.

“Ah~ Sarena-chan,” he sighed. “Sensei feels dizzy~ how about we go out for lunch?”
