Room 2-B had a reputation. Not for brilliance or discipline, but for its daily circus of loud laughter, playful pranks, and a general lack of respect for authority. It wasn't that the students were mean - at least, not intentionally. They just didn't take anything seriously, especially not teachers who showed even a hint of softness.

And Ms. Reyes was all softness.

She was young, new, and painfully polite. Her voice barely traveled beyond the first few rows, and she had a habit of smiling nervously whenever the class got too loud, like she was trying to calm a storm with kindness. It didn't work.

Each day, the students pushed a little more.

"Miss Reyes, did you get that sweater from the 1950s?" Jayden would joke, flipping his pen between his fingers like a magician.

"Do we get points for staying awake today?" murmured Trixie, pretending to yawn loudly during the roll call.

They laughed - not maliciously, just... carelessly. They didn't see the way Ms. Reyes's smile faltered before she regained composure. They didn't hear the slight tremble in her voice when she turned back to the whiteboard.

But Leo saw.

Leo didn't sit in the front or the back. He sat near the window, halfway down the row - close enough to hear, far enough to disappear. He was round-faced and heavy-set, with glasses that always slipped down his nose and a habit of scribbling galaxies into the corners of his notebook. He barely spoke in class unless called upon.

No one teased Leo directly, but no one talked to him either. He was just there. A background character in their daily sitcom.

Except today.

Today, Ms. Reyes looked especially tired. Her bun was a little looser, and her usual lipstick was missing. She seemed distracted, like her thoughts were miles away.

As she wrote "Literary Devices" on the board, Jayden raised his hand lazily. "Is 'bored to death' a metaphor, or just how I feel every time you start talking?"

The room erupted in laughter.

Ms. Reyes turned, gave a weak smile, and continued. But Leo's hand gripped his pencil harder. His stomach twisted.

He didn't know why it bothered him more today. Maybe it was her eyes. Or the way she seemed smaller than usual, like she was shrinking from the noise.

He stared down at his notes - lines and circles forming a spiral galaxy - then took a breath.

"Hey," Leo said, his voice quiet but steady. "Can you guys just? stop?"

The class froze for a beat. Then came the snorts.

Trixie turned around, raising an eyebrow. "What was that, Leo? You defending the teacher now?"

Jayden smirked. "Didn't know you were into Ms. Reyes."

More laughter.

Leo's face burned. His chest tightened. He felt like he was shrinking now. But he didn't sit down.

"She's just doing her job," he said, louder. "You don't have to be so mean all the time."

Jayden stood up theatrically, clapping. "Wow. Leo speaks! Mark your calendars, people!"

"Guess our boy's found his courage," Trixie added. "Or maybe just trying to get a better grade."

Leo sat down, trembling. His heart pounded so loud he could barely hear the rest. He avoided everyone's eyes, including Ms. Reyes's.

But Ms. Reyes saw everything.

She didn't say anything right away. She simply walked back to the front of the class, picked up her marker, and continued the lesson. Her voice was still soft, but stronger than before.

"Let's move on to personification," she said, turning to the board. "When we give human qualities to non-human things."

No one joked after that. Not for the rest of the period.

When the bell rang, students filed out like usual, chattering about lunch, video games, or whatever was trending online. Leo stayed behind, pretending to pack slowly.

Ms. Reyes looked over.

"Leo?"

He froze. "Yeah?"

She smiled - gently, gratefully. "Thank you."

He didn't know what to say, so he just nodded. His face was still red, but something in his chest felt lighter.

The next few days were quieter. Not completely respectful, but not as loud either. The jokes returned, but with less edge. Leo still sat by the window, drawing stars, but now there were glances - curious ones. Some students started including him in conversations. A few asked to borrow pens. Trixie even passed him a note during class that said: Braver than I thought. Not bad.

He didn't reply. He just smiled.

And Ms. Reyes? She stood a little taller, spoke a little louder, and stopped smiling just to hide discomfort. She even started adding bits of humor to her lessons - clever, subtle things that made the students laugh with her, not at her.

It wasn't perfect. It wasn't magic. But it was better.

Because sometimes, all it takes is one voice to shift the room.

Even if that voice shakes.
