(Caption) The Euphonium Girl

In the room, the afternoon sunlight slipped quietly through the half-closed curtains, spreading across a desk piled high with sheet music.

He sat there, staring at the brass instrument in his hands - a keepsake from his mother. It was an old-fashioned euphonium, delicately detailed, faint floral patterns carved along its edges, as if it carried the echoes of time itself. Yet no matter how hard he practiced, the melody always lacked a soul. The pitch was correct, the technique precise, but that gentle yet powerful tone his mother once had - he could no longer reproduce it.

He gripped the instrument tighter, his fingers trembling. It was anger, but also helplessness. Lifting his head, his eyes glimmered with tears as he drew a deep breath.

"Why... why can't I even come close to her?"

His voice quivered, fingers whitening from strain. The next moment, he pressed the mouthpiece to his lips and blew with all his strength.

In an instant, the air seemed to tear apart.

Boom-

The sound burst from the euphonium, shaking the entire room. The curtains fluttered, sheets of music rose and scattered. The wave of sound was so intense it ripped his clothes apart, fabric bursting into tiny fragments.

But the fragments didn't fall. They spun and shimmered in the air, glowing faintly as they formed floating staves around him. Notes began to flow across them, light and sound blending together into a living symphony.

He stared in awe - it felt like his mother's hands were guiding him forward.

He lifted the euphonium again, pressing his lips gently to the mouthpiece.

Notes leapt one after another, and the swirling scraps of fabric began to move in rhythm. The first pieces wrapped around his legs - soft purple stripes weaving together into over-knee stockings, smooth and snug against his skin.

Next came layers of vivid fabric swirling in the air, folding and spinning into a pleated skirt of red and blue, gleaming like stage lights. Over it appeared a pink jacket and a green tie - bright, cheerful colors born from the very music itself.

The glow from the euphonium grew stronger, and he felt his hair shifting like liquid light.

The vibration swept from his crown downward, his short hair flowing and lengthening into soft waves of lavender cascading over his shoulders. Bows and candy-shaped clips sparkled in her hair, like melodies turned tangible.

Her face softened - lashes long, lips curved in a gentle smile - as though the sound itself had sculpted her expression.

The rise and fall of her chest carried a new rhythm, a new weight. She blinked, startled for a heartbeat, but kept playing. In that moment, her music was more beautiful than ever before.

When the final note faded, the light dissolved.

She stood still, surrounded by silence. The polished euphonium reflected her image - long hair flowing, a warm smile on her lips, and in her arms, a small white rabbit plush with a bow, the same one her mother used to place on her music stand. Now it rested quietly against her chest.

She laughed softly, tears gliding down her cheeks.

"Thank you, Mom."

At that moment, she finally understood - music was never about skill alone, but the resonance between hearts.

So she straightened her back, gently brushed her fingers along the euphonium, and spoke with calm determination:

"I'll become the best music boy... no, the best music girl."

Once again, the room filled with melody - sweet and clear, as if her mother were right there beside her, smiling and listening.
