In the heart of a bustling little town, a child of four named (Y/n) (L/n) often found himself lying in the grass, gazing at the stars in wonder. The world was vast and magical, a playground of curiosity and innocence. One fateful night, as the sky shimmered with celestial wonders, (Y/n) spotted a shooting star streaking across the velvet canvas above. In that moment, he closed his eyes tight and whispered his wish, a simple plea to be more than just a child.
"I wish I could be grown up," he murmured, a desire inspired by the thrill of adventure he imagined in the lives of teens around him.
However, no one warned him about the cost of wishes. The next morning, (Y/n) awoke not as a toddler but as a 17-year-old young man, his body tall and his features defined, yet his heart was still that of a child yearning for simplicity. Confused and filled with a sense of dread, he learned he must journey to Union City, where the unique Kurosu World High awaited—school for heroes in training where the extraordinary was the norm.
As (Y/n) stepped into the bustling halls of Kurosu World High, he felt the overwhelming weight of his newfound identity crash upon him. Students swarmed in colorful uniforms; some eyed him with intrigue, others with wary suspicion. It didn't take long for whispers to float through the air, both flattering and menacing.
"Look at him, he's different..."
"What's his story?"
Caught in the whirlwind of adolescence, (Y/n) tried to navigate the expectations that came with being a hero-in-training—learning, fighting, and making friends while battling the constant memories of his cherished childhood. However, entangled in this chaos was a deeper struggle—the blossoming feelings he harbored for a classmate named Yagyuu.
Yagyuu was stunning, standing out with her fiery spirit and unwavering confidence. (Y/n) couldn't resist the magnetic pull he felt towards her, yet the burden of his secret—a wish that had irrevocably changed his life—twisted inside him like a storm. Afraid of losing her once she uncovered the truth, his heart battled fiercely with emotions he couldn't comprehend.
On a quiet afternoon, as they shared lunch on the rooftop under the expansive sky, (Y/n) found himself unable to contain his feelings any longer. He stood, heart racing, the words tumbling from his lips in the form of song—a melody straight from the soul.
(Y/n):Oh, girl!
In a world turned upside down,
Once a child, now I stand my ground,
I made a wish, and it came true
But deeper feelings, I never knew.
The breeze carried the notes, painting the air with his truth—a vulnerable confession resonating in the silence between them.
As he sang, (Y/n)'s voice trembled with emotion, revealing the turmoil within.
(Y/n):My heart's a storm,
just raging inside,
Afraid if you learn,
you might run and hide,Got this crush, oh,
it's tearing me apart,
Every glance, it's like a spark in the dark."
(For a fleeting moment, he witnessed Yagyuu's surprise transform into intrigue as she listened, her eyes wide and glistening with unshed tears. The world around them faded—the noisy chatter and laughter of other students became a distant hum.)
The chorus erupted from (Y/n)'s lips like the climax of a long-held breath:
(Y/n):Oh, oh, oh,
I'm being torn apart!
I wish that I could tell you,
'Bout the storm that's in my heart.
Each note floated away, leaving behind a lingering silence as Yagyuu stepped closer, her expression changing from surprise to understanding.
The fear still clouded him—what if she hated him once she learned the truth? But as he observed the glimmer of compassion in her eyes, a flicker of hope ignited within (Y/n). This battle inside him needed release, and he had dared to show her the tempest brewing within his heart.
Yagyu:(Y/n)...
she began, her voice a soft lullaby,
Yagyu:you're amazing just as you are. You don't have to hide. I care about you, the real you."
As the sun dipped low, casting golden rays around them, (Y/n) felt a profound sense of relief wash over him. Perhaps this wish had granted him not just the years he longed for, but also the courage to love and be loved, despite the chaos swirling around.
In a world turned upside down, he found himself not as just a young man but as someone worthy of connection, forging a path toward the bright horizon ahead—one that no wish could ever change.
