The sun dipped below the horizon, casting long shadows across the training grounds of Jujutsu High. Y/N Gojo stood on the balcony of the teachers' lounge, staring out into the distance. The sounds of laughter and camaraderie from the students below faded into a distant hum, replaced by a familiar ache in his chest.

It had been years since Suguru Geto had walked these halls, yet his absence weighed heavily on Y/N. The memories surged forth—laughter shared, fierce debates, and the camaraderie that had once defined their friendship. They had been brothers in arms, two sorcerers bound by a shared vision of strength and purpose.

Y/N leaned against the railing, lost in thought. He remembered the days when he and Suguru trained together, their rivalry igniting a fierce desire to push one another to new heights. Suguru's unwavering determination and charisma had drawn people in, but beneath that surface lay complexities that Y/N had never fully understood until it was too late.

"Hey, Y/N!" Satoru's voice broke through his reverie as he joined him on the balcony. "What's got you so deep in thought?"

Y/N turned to his brother, forcing a smile. "Just... thinking about the past. About Suguru."

Satoru's expression softened, the playful glint in his eyes fading into something more serious. "I know it's tough. We all miss him."

"It's not just that," Y/N admitted, feeling the weight of his words. "I've been thinking about how things changed. He had such a different vision for our world, one that I couldn't understand back then."

Satoru leaned against the railing beside him, his presence a comforting reminder of their bond. "Geto was always complex. He believed in strength, but he took it in a direction that led him down a dark path. It's hard to reconcile the person we knew with what he became."

Y/N nodded, recalling the conversations they had shared late into the night, the ideals they had fought for together. "I thought we could change the world together, but... somewhere along the way, we lost each other."

Satoru sighed, looking out over the grounds. "You can't blame yourself for his choices. We all have our paths. Some lead to light, others to darkness."

"But I had a chance to reach out to him," Y/N said, frustration creeping into his voice. "I could have done more to understand him. Maybe if I had, things would have been different."

Satoru placed a hand on Y/N's shoulder. "You can't carry that burden alone. You did what you thought was right at the time. We all did."

The weight of Satoru's words settled over Y/N, but the ache in his heart remained. He couldn't shake the feeling that he had failed Suguru, that their shared dreams had slipped through his fingers like sand.

"Sometimes I wonder if he ever thought about us, about the bond we shared," Y/N confessed, his voice barely above a whisper.

"Maybe he did," Satoru replied, his tone softening. "Even in the end, I think he still cared. But he chose a path that separated him from us. We can't change that."

As the sun set, painting the sky in hues of orange and purple, Y/N found solace in Satoru's words. "I just wish I could talk to him one more time. To understand what drove him to that point."

Satoru's gaze hardened slightly. "You're not alone in that. I still have questions too, but dwelling on it won't change the past. We have to honor his memory by forging a better future."

Y/N nodded, a sense of determination igniting within him. He would carry the lessons learned from Suguru, both the good and the bad, into his role as a teacher. The bond they shared would not be forgotten; it would fuel his resolve to guide the next generation.

"Let's focus on what we can do," Y/N said, a newfound strength in his voice. "We'll teach our students to stand against the darkness, to understand the value of strength without losing themselves in the process."

"Exactly," Satoru said, a smile returning to his face. "And if they ever encounter someone like Geto, they'll know how to make the right choices."

As the stars began to twinkle overhead, Y/N felt a sense of peace settle within him. Suguru may have been gone, but his legacy would live on through the lessons imparted to the students of Jujutsu High. Together, he and Satoru would ensure that the mistakes of the past would not be repeated.

With a renewed sense of purpose, Y/N turned back toward the training grounds, ready to face whatever challenges lay ahead, knowing that the bond he shared with Satoru would guide him as they shaped the future of jujutsu sorcery together.
